3500 Cab and Chassis Rear End Squat Under Load??

[HBarlow]

Question for EB (or other owners):EB, what is the approximate unloaded coupler weight of your tandem dual gooseneck trailer and how much is it when your trailer is loaded?* How much does the rear suspension of your truck squat when loaded?The reason I ask is I have been disappointed with the relative softness of the rear springs of my 3500 dually pickup. * It sags several inches under the kingpin weight of my own 5er or some of the heavy trailers I have pulled when working. * I use Timbrens and recently had to have the rear springs rearched and an extra leaf added. I notice that the rear spring pack of a cab and chassis is very different. * It has several more leaves than the pickup although both trucks have the same GAWR of 9,350#. Harvey

Hey Harvey I just came across this and have been thinking of giving it a try. The claim is more capacity, but yet a much better ride. E-ZrideCorp.com - Home

Check this addition out. It works for me.

Karl,



An interesting product but I can't understand how the flexible rubber parts have much effect. I watched the video and thought about it a little and I wouldn't think the rubber bumpers would have much strength or resistance in that direction. I could see it if they were being directly compressed but they're just being bent. I don't get it. Let us know how they work if you try them.

CUMMINZ,



A great idea. Simple, effective, and cheap. You should patent the idea and market it.

The pin wt. of my trailer is between 25 and 2600 lbs. empty. If I load it to our max. wt. of 15k it would be an additional 3750 if I am able to get it loaded right and transfer 25% of the weight to the truck. Some of it would be shifted to the front axle, but most would be in the rear, somewhere between 5 & 6k on the pin. It goes down some but not nearly as much as my 03 did. The springs on the cab and chassis are definitely stiffer. I do plan on getting air bags as soon as someone makes them for the cab and chassis, no one does at this point that I've found.



That idea that Cumminz has looks pretty good. Might try that if I can find some of those high dollar splitters he is talking about.

EB,



Thanks for the reply. Your 3500 sounds like a good truck for your needs and mine as well.



Based largely on your experience and reports of the performance of your 3500 Cab and Chassis I have ordered one. I thought I really wanted a 4500 but I'm disappointed to recognize they are not intended for an RVer who drives his truck part of the time as personal transportation.



From what you have told me about the rear suspension and weight carrying capacity of your 3500 I should be pleased with mine. The pin weight of my own 5th wheel is about 3,700 lbs. and with my Transfer Flow fuel tank, tools, etc. I should have around 5k on the rear axle.

I don't think they will work on your C&C because you don't have the overloads like a normal 3500. The C&C doesn't have the overloads... (As I understand)

I bought the Firestone Air-bags for around 250 in houston and installed them myself in about 3 hours. If you get the air-comp. kit it will cost you another 250, but well worth it to be able to control the lift(ride) while you ride down the road.

 

[RVTRKN]

I added this bed on my C&C and didn't notice too much of the squat your talking about and the ride is exceptable but watch out on the speed bumps or it will launch you into orbit. The truck weighed #9500 after install and I'm happy with the setup, but would like to add airbags when available as EB stated in an earlier post. It pulled my 5ver without squatting as well, although its weight is around 9K, and I dont know the pin weight. I don't think you will have a problem as long as you keep the bed weight to a minimum. Sorry I don't have better pictures with the 5ver attached. Also I ordered it with the super heavy duty front springs if that helps you any.

KWayne,



Thanks for the info. Is your truck also a 3500 cab and chassis? Was the airbag kit designed for the cab and chassis or did you have to adapt it?

RVTRKN,



Thanks for the information and photos. That is a good looking B&W bed. I called B&W last week to price their beds. Their price is pretty steep! I don't want to pay as much for a bed as they want for theirs although they obviously build a quality product. Their beds also would not permit installation of my 70 gallon Transfer Flow fuel tank. I decided on a more "budget" basic flatbed from CM in Madill, OK. Not anywhere near as fancy but will be functional and I can hang large storage boxes underneath.



After posting my question here about rear end squat I stumbled upon a useful bit of information over the weekend on Dodge's Upfitter website. I found a chart of measurements for each of the cab and chassis models with the distance measurement from top of rear frame rail to ground unloaded (31. 5")and top of frame rail to ground loaded (28. 6"), a difference of only 2. 9". I assume loaded means loaded to max GVWR although I guess it could mean loaded to full rear GAWR. That's not a lot of squat. It's far less than what my 3500 dually pickup does. Without even knowing that number I ordered the cab and chassis hoping its springs were a lot stronger than a dually pickup.



How do you like your cab and chassis? Have you put many miles on it yet?

Yes, I love the truck and bed as well, I know the B&W bed was not cheap but their quality shows in the workmanship and in my opinion they are second to none. B&W took good care of me from the start and even though it took a long time to build, but only because of demand. The reason I chose B&W was due to the fact they had two on display at the Rodeo in Vegas with the C&C Laramie QC 4X4 and saw the quality and dual purpous of the bed that I needed. You could not find a Laramie C&C any where except at the Rodeo, even at the LA auto show



The C&C has been flawless even though I only have 11K miles. The trip to Kansas to get the B&W bed was a joy with Nav & Sat to help out. The C&C's are not having the DPF issues like the regular trucks and will be a good choice on your part. Feel free to PM me if you have other questions.

RVTRKN,



Thanks. You and EB will be hearing from me when I get mine. I just ordered it a little over a week ago so I've got some time to wait.

I don't think they will work on your C&C because you don't have the overloads like a normal 3500. The C&C doesn't have the overloads... (As I understand)



Merrick

You're right, won't work. Guess I'll have to wait for some air bags to come out for the cab and chassis.

 

[HBarlow]

Huh? I'm confused. The cab and chassis trucks I've seen all have overloads on them. What am I missing?



Harvey

Harvey

The cab and chassis does have overloads, it is just a different spring pak setup than the pickups have. That is why the splitters won't work on the C&C. There are some pictures around here somewhere that shows the difference in the two, I just don't know where they are.

 

[MCummings]

Ok, I was a little confused, but here's the beef.

The 3500 C&C + don't have the fat flat overload's like the 3500/3500's have.
