Gents,



A T. Rex Baja Trip is officially in the works! More details to follow.



Sorry, 2wd guys, nothing for you, yet. There's just not enough space to get massive, race-sized dampeners on the truck. By the way, 2wd works really well in certain off-road situations - sometimes much better than 4wd. But, unlike you guys, most 2wd guys are pavement oriented. We've had a lot of requests, but, after much reflection, not enough to make it worth engineering a complete system. Perhaps in the future.



CFast, I've been through the San Joaquin Valley many times - the 99 is notorious for bad expansion joints - especially in the slow lanes because that's where the big rigs have to stay. I've been going to Yosemite about six times a year for 20 years, so I've driven that road from Bakersfield to Fresno many, many times. It's very bad.



Suspension is a tough subject because everyone has different expectations. T. Rex suspension is custom stuff, so sometimes it takes us a couple of tries to get it just right for a customer. My personal taste is a truck that feels just like a sports car on the pavement - meaning no body roll and tight, responsive steering that gives a lot of feedback from the road. In a word I would call this a "taut" valve profile. This tight setting, translates into minor expansion joint sensation that is largely due to a combination of hydraulic resistance from the shock and the normal harmonic that develops from big springs, 8000 lbs. of rolling mass and lots of unsprung weight (a load bearing vehicle). It feels much better than stock, but the bumps are not totally eliminated. In addition, this setting moves the expansion joint "sweet spot" (the speed at which the sensation totally disappears) to about 80mph - depending on the freeway. A little fast for most people.



Some of our customers prefer a looser, more cushy ride - more like a luxury car. If I had a word to describe it, I would call this a "plush" setting. This is what I would recommend for you. Your truck will ride like a big Mercedes. Smooth and controlled. Some of our customers have said that their expansion joint woes are completely eliminated with this setting, others have said that they can still feel certain sections, but the sensation is deadened. I find that this setting, when running empty gets rid of about 80% of general freeway expansion joint bumps, leaving about 20% you can still feel, but those you feel are much softer. The "sweet spot" for this setting is about 65mph, depending on where you're driving.



We've found that there are certain stretches of freeway that are just murder, no matter what vehicle you're in. Even if you're in a car, they're terrible. The 10 freeway, near Banning, CA (going to Palm Springs) is heinous and the 5 freeway (especially heading North) near Tustin, CA come to mind. California is a nice place, but, man, we've got some bad freeways here! These spots are especially bad because the joints don't have sharp edges between them, so they hardly move the suspension! It's the angle that changes slightly between each joint, rapidly loading and unloading the truck with slight positive and negative G that a truck's chassis just doesn't like because it's so heavy and unyielding. At certain speeds it feels like a big, fat Swedish Masseuse is continuously Karate chopping your kidneys! I don't care if you're driving a Lexus! Our suspension makes her a lot more gentle that your stock truck, but on certain small sections of freeway she'll still be there, giving you the business.



Anyway, both of these settings have advantages and disadvantages off-road. I like the "taut" setting for winding mountain roads and high-speed sand - like San Felipe. The truck feels really stable and takes the big hits like nothing. Wheel hop and axle wrap go away, which enhances acceleration through the corners. It's also really fun to air out the truck without damaging it. Either intentionally or inadvertently...



The off-road advantage of the "plush" setting is on the high speed washboard. It just rolls over this stuff like you're on a smooth highway - sometimes even better than a highway - because this is still hard-core off-road suspension and this is where it's at home - made for fade-free performance for thousands of continuous miles. The preponderance of the systems we sell come with the "plush" setting - or special valving, that after much discussion with our clients, we've determined will work best for them in their particular environment.



This was mostly a discussion of T. Rex Engineering's suspension relative to T. Rex Engineering suspension. Relative to OE or any other aftermarket product, even the "plush" setting will give you better cornering, reduced wheel hop, and a more stable feel in addition to the kinder ride over expansion joints.



Now, your real question is, "should I sell my 69' Charger to pay for some T. Rex Engineering suspension. " My answer to you is this, "not if you're just going to drive the freeway. " This is ultra high performance OFF-ROAD suspension. This is where T. Rex works best.



Interpretation of suspension performance is subjective at best, but for the sake of discussion, we'll say that our suspension, no matter what valving you have, increases the speed you can _comfortably_ drive over a certain section of rough terrain from 15mph to 50mph. That's a big improvement - and not unrealistic at all. And, depending on how often you're in rough terrain, it may be well worth it to spend not a small chunk of change to get that kind of performance. Most of our clients use their trucks regularly off-road, so they're tickled to have T. Rex Rams. But the freeway is a different story - take that section on the 99 that's kicking your butt. Do you want to spend 3. 5 Large on performance suspension just so you can drive the freeway at legal speeds? It would be like flying an F-18 straight and level at 120 knots, when the thing is just begging to do 7 G pulls and hit 1. 8 Mach! Why spend money on an F-18 when a Piper Cub will work just fine for slow, straight and level flight?



I think what I'm trying to say is that while we would love to sell you an incredible suspension system, I can't tell you with absolute certainty that the pavement benefits alone will make it worth every cent you pay. For some of our customers it is worth it - especially because there seems to be no other way to get these trucks to feel decent on the road. Is it right for you? Will your wife call and thank us after you get it on your truck? Some of our customer's wives have! But I can't tell you that the expansion joints on the section of the 99 that you're driving with _your_ truck with _your_ tires and _your_ pressures at _your_ speeds will magically disappear. I haven't driven with you under _your_ parameters so, unfortunately, I can't promise you anything. The bumps may go completely away - or they may not. They will be absorbed _better_ with our product. But we will feel terrible if you buy the most advanced off-road suspension available and the pavement ride isn't better _enough_ to warrant its cost.



I'm the V. P. and in charge of Marketing and Customer Relations, but, as you can see I'm no "Salesman!" We shoot straight around here. We've got a very unique product and for some people it's literally priceless to have it on their trucks. But I don't think it's for everyone.



Please don't hesitate to call us for more info. We can also put you in touch with people who are using our suspension. We think their opinions are often worth more than ours.



Best Regards,



Kent
 
Thanks for the reply Kent. I've been talking to other people on here that have your suspension and they all say it's great. Some say it's the best thing on thier trucks. I just want to make myself more clear. I DO plan on using this off road, that's why I bought a 4x4. I never expected a "big Mercedes" for handling or ride. I've read all the posts in this thread and I feel like I should buy your product just because of all the work you've put into responding to people. :) As far as selling my 69 charger:( , that's going to happen no matter what. Just starting my family,so some toys have to go. :( I plan on keeping this truck FOREVER. What i'm saying in here is, I'm sold and the wife is sold on this suspension. I won't have time to call this week, but next monday I'll be in contact with you guys to work something out. Thanks for all the info. Clay
 
Hi Kent,



My name is Greg Boardman, I live in Twentynine Palms, Ca. I own a 2003 DRW 4x4 that rides real rough. I read earlier that you said the 19. 5's don't do your system justice. If I was to install the system on my truck would I still be able to tow heavy loads and enjoy the taut setting? I plan on trading in my truck soon enough to get a 2500 4x4 SWB quad cab. From there the fun will begin. Will I be able to switch out the stock shocks back to the 03 and have you revalve the Kings for the new truck? I have been very interested in this system since the begining. Dan called me after he rode with you and said I needed to sell my truck. Can the system work ok on a Dually? Thanks, Greg
 
Clay,



I just wanted to make sure you would enjoy the full benefits of our system and not be disappointed in any way. We really try to be up front with people. Good to know you'll be getting your truck in the rough from time to time. You'll be blown away by its new capabilities.



Greg,



You're out in the high desert. Beautiful this time of year. I lived in your town for about a year and loved it. With an endless supply of high-speed dirt roads out there, your geographic location makes you a perfect candidate for a some racing suspension!



The 19. 5's and our suspension don't mix well. That's a fact. Commercial tires are a great idea for increased safety and longevity - especially if you regularly go past your GVWR. But our experience with them + T. Rex is that, yes, it _works_ (functions) together, but not optimally. And we're all about getting the max performance we can out of a given vehicle. If you are in a constant heavy load condition, that is, with a large camper or 5th wheel always on the truck, you may love the reduced sway and increased control of the 19. 5 + T. Rex combo. But I doubt you would like to cruise up to LA on the 10 with nothing but air in your bed. We've tried it with a 19. 5 dually, making enormous changes in the valving - and the expansion joint ride is just not very nice. The truck feels really good on normal roads, it's just the repetitive freeway junk that the combination of steel sidewalls and 2. 5" steel-bodied shocks don't like.



So to answer you question - yes you would be able to comfortably tow heavy loads with either the taut or plush setting - or any valve profile in between. The valve settings we provide don't affect your ability to carry loads, they're just a matter of ride taste. Compared to OE, a huge race shock with even our plushest setting is still doing so much more work to maintain the stability of your vehicle, there's just no comparison.



Without removing our springs or stud rings, you can slap the OE shocks right back on your truck, send us the shocks and we can tune them to your taste or when they're transferred to a new vehicle that has different performance parameters. We provide this service free of charge. We love when our customers get their shocks back from tuning and they say their ride is "just right. "



"Tuning a shock" may sound a little strange to most people, but to racers it's as common as an oil change. And that's another nice thing about our suspension. You buy it once and it never wears out. From seals to oil, every part can be quickly and inexpensively replaced.



Our systems work great on duallies. We've got lots of satisfied customers who drive T. Rex duallies.



Hope this helps.



Kent
 
So what you really need to develop now is a remote cab adjustable system so we can have the best of both worlds. :D



Of course dynamically adjustable shocks are probably not all that cheap. :(
 
is there any news on another version of these shocks being developed and if so what are the anticipated differences like price, performance, application, and availability, etc.



regards,
 
Baja test of T-Rex system

I jusr returned from a 5 week trio to Baja, my first chance to test out my new T-Rex suspension. I have a heavy expedition camper, built up on the frame a a 3/4 T chassis cab, and I pulled a trailer w/ dune buggy, kayaks and inflatable boat. The trip was over 3000 miles, we went as far as LaPaz and spend much or our time off pavemant. With one section from Bahia Los Angeles to Viscaino being over 175 miles off pavement. another section of 75 miles of severe rough road from Constitution to Tambabiche, and several roads of lesser length. My evaluation of the T-Rex system: off pavement- excellent, very greeatly improved comfort [my wife loved the ride] and at increased speed. Example- 7. 5 mi. of washboarded gravel between Ej. Ambrulo to Hwy 1, last yearw/o t-rex ave speed 15mph, this year with 30 to 35 mph! another example- road north of Agua Amarga dry lake much faster and more comfortable than in the accompanying vehicle (Ford F250 4x4). Off pavement is where this system really shines on a heavt truck like mine(12000lbs) ON pavement- Baja pavement- these are rough by U. S. standards, narrow, have potholes and eaten away edges of the pavement. I had better control, less roll, and fewer problems when a wheel got over the edge of the road, more stable wen psassing and when meeting on comming big rids. Define plas over stock! On road -U. S. On freeways the ride is better and there is less "joint bounce" We made better time than usual and felt more rested and relaxed. ( this was a run from Orange Co. to the Monterey area , up I5. The t-rex system isd plus on my heavy truck on this kind of road but not as dramatic of an improvement as on the other types of surface. I noticed one post by member that complained about rideon Freeways, he should call Kent at T-Rex , if what he says is true, then that trucks system needs to be adjusted. Kent customizes the shocks and springs to your truck weight ( needs total weigh and front and rear weights loaded) and also to your use. If it isn't right get back to hime, he can revalve the shocks and fine tune it for your rig and use. Summary of T-Rex---Off road- great fabulous, rough road great improvement, U. S. standard roads- improved comfort. My recomendation for those with heavy camper trucks-- if you use your truck off pavement extensively, this system is the best I have seen and is well worth the price! If you only occationally fo off pavement or only short duration or rarely use you truck that way--then you have to look at the cost vs. the benefits. If you bought a 4X4 for real off road then this system is really great!! Note for anyone interested I have been going to Baja since 1959, normally my wife and I spend 5wks at Christmas time and 2 months in the summer in Baja. My rig is a self built expedition type camper on a chassie cab. It is heavy because we carry enoth supplies to last for more than a month at a time without resupply, water is heavy! One small sad note , the truck went so well with this system that I did some real damage to my trailer, pulled the shocks on the trailer apart, and many thing need to be rebuilt! I have obtained King shocks for it and I plan to rebuild it to be able to stand up to the trucks great new performance!
 
Last spring, I bought a slight used 02, extra cab, RAM CTD, 4x4, HO with a 6-speed manual because it was the truck of my dreams. With a growing family, my old 94 gasoline, standard cab RAM had outlived its usefulness.



After owning the truck for few weeks, I quickly learned that the vehicle's ride was much stiffer and more uncomfortable than my old rig and it had a tendency to float around the road. My lower back was bothering me and I was beginning to question my purchase decision.



Wanting to improve the ride as well as having dreams of racing the Baja 1000 (or at least pretending to) I started looking at my options for suspension modifications.



I looked at all the major manufacturers and many of the lifts were pretty tall and required some pretty significant modifications to the truck. A friend of mine had gone this route and had nothing but long term problems because of the significant changes made to the original factor angles, etc. I quickly decided that what I really wanted was not height, but rather something that would really allow me to use my truck the way I wanted. That is, driving really fast on really rough, dirt roads. The taller the truck gets, the less stable this becomes.



My original plan was to simply get a set of new coils for the front with some really good shocks. I then realized that I didn't know anything about shocks or valving and most of the aftermarket shocks for the CTD had the stupid pin-type top mount. There really wasn't a viable aftermarket shock or mount that I could find that was going to allow me to do what I wanted to do.



It was right around that time that I saw the posting on T-REX and was immediately hooked, until I saw the price. It was almost a deal breaker. I am a really frugal guy and hate to spend money.



I had many long conversations with Kent about the benefits of the suspension, but I just couldn't get over the sticker shock. It was keeping me up at night. Finally, I just decided that by the time I had spent money on aftermarket coils, learned about shock valving, bought new shocks, had custom shock mounts built, re-did everything because I screwed it up the first time, etc. , etc. , I was going to be spending more in the long run that if I had just bought a T-REX system. I should also mention that I had an upcoming trip to Baja already scheduled, and I wasn't going to go back with the same old crappy stock suspension. So I took the plunge.



The first thing I noticed was how the expansion joints on I-5 were virtually eliminated as we headed south. The truck was also more firmly planted to the road. No more floating or drifting all over the lanes.



Once we hit Baja, that is where it really excelled. We went down the week after a major hurricane and roads that were previously considered really bad, were now considered heinous to impassable. I decided that I was only going to live once and put the hammer down to see what this new suspension was going to do. WOW!!!!!! The ride was amazing. Washboards were a thing of the past. The suspension just soaked it all up.



For those of you who have driven washboards before, you know that when you hit a certain speed, the bounce seems to go away. HOWEVER, when you are accelerating to get there, or trying to slow down from that speed can be quite frightening and down right bone jarring. With the T-REX set up, I actually had full control both accelerating and braking through some of the worst sections of washboard I have ever been on. Off the main sections and into the sand washes, the wheels, once again, were firmly planted to the ground. No more wheel hop when taking off in the sand.



Sections that had previously taken a 2-3 hours to navigate, were now taking an hour... ... ... ... ... ... ... under worse conditions. Best of all, I could drive like that all day because the ride was much easier on my body. The shocks handled the worst I could throw at them for days on end and the performance never diminished.



I almost felt bad for my friends behind us who were eating our dust, listening to the skipping CD player (ours skipped only once), and wishing they had kidney belts.



My truck is basically stock, but the suspension change that I made has been the best money spent. I can honestly say now, that I really don't even think about how much I spent.

Another point that needs to be emphasized is that Kent can and will tune the T-Rex suspension for your truck weight ( mine is very heavy) and for the roads you use it on and for the way you drive. He assured me that if we didn't get it right the first time he would retune until it was just right. I believe my truck was one of the first that was real heavy and used extensively on very rough roads that he has done. The result was remarkable, and my wife says it was one of the best things we have done to the truck! The kit was not difficult to install for a good backyard mechanic and comes with good instructions.
 
T-Rex/Baja Proven

Great read on your adventure and description of the T-Rex Suspension... I have brutally abused the T-Rex Suspension in my 99 4x4 and it continues to perform... Having said that, in November 2003 I pre-ran the Baja 1000 three times working for BFG/SCORE... just that trip alone was over 2500 miles off road.



We have tested the T-Rex Suspension like no one else that I'm aware of and it has performed like I would have never believed. Check out one of our latest adventures here...



T-Rex Conquers the Baja 1000
 
Question,

According to the T-rex website they have a package for the First Gen trucks. Anyone have this kit (or any T-Rex parts) on there old dodge? Is the ride improvement just as amazing?

Thanks,

John
 
Heard from Kent that T-rex was going to be at May Madness this year. I'm going to try and scope out a demonstration route near the speedway this week. He wanted about 5 to 10 miles, and as rough as I can find... He is planning on about a 10 minuted demo ride :)

Greg
 
I would be interested in a lesser version also. . I realy don't need the full blown system, just one to take care of speed bumps and frost heaves...
 
Ice scrapers?

Kent,



I noticed on your sight you have king and fox shocks which ones come with the second-generation kit? Living in Alaska I have a concern about shock seal life. I read in your earlier post that you did some testing Colorado to test that aspect of the shocks. But my truck see's some extreme temperatures and many harsh frozen dirt roads covered with snowdrifts. Speaking purely form my experience with rebuild able fox, Olin etc snowmachine shocks the shaft seals are the weakest point on the shock and ice forming on the shaft is the big enemy of the seal. Fox and Olin both have a ice scraper style seal that they now use on there sled shocks to scrape the ice off the shaft before it can reach the seal. Do the Fox, and King shocks you are using have anything like this? How do the shocks handle -35F to -50F and the big temperature swings that happen from the shock warming up to operating temperature from these cold temperatures on our frozen dirt roads?



These are just a couple questions I had but I must say you have what looks to be a most impressive system. And on a side note Kent if you don't have any real life experience of your system operating in these types of conditions let me know and maybe we could work something out. :D



Keep up the great work and if I'm ever in your neck of the world I will definitely swing in for look.
 
Hemiless -

when I purchased my T-Rex I had the choice of either King or Fox systems. I opted for the King. As I understand it though, I believe the T-Rex guys have had much better customer service success with Fox.

Having said that, I love the King shocks. My truck has seen some very cold weather this winter and I have had no problems. We don't have the high humidity that you probably have but I have had no problems operating at well below zero.

Hope this helps a little bit,

Jason
