Lol, well good. I can't wait for you to outdo me on the suspension and show me hows it done!!!

Well... haha. After a little thinking, I think I am going to can the leaf front. I have a few entire front ends (meaning from the coil buckets down) from 2nd and 3rd gens that Ive cut off trucks at U-pull it, so I think instead of investing money into Alcans or 52's up there, Im going to coil it and then run thuren coils.

I dunno... I cant decide. The 52's will be easy and I would assume they will ride better than the 47's. Im just afraid its going to be too tall with any of the 52's by the time I move the shackle hanger back ~2" (which makes it lower on the frame), and then run a shackle long enough to let the springs work. Id like to stay ~3" or lower.

The other trucks Ive put 52's on were gas trucks, and the height was wanted.
 
Havent updated this in FOREVER. The body is all on, wiring is ~90% done, Got the new turbo and stuff on it (did a hx35 with a 14cm housing with a banks WG actuator), etc.



I actually started it yesterday! I need to do some work to the steering box bracket, A little more wiring, throw the dash back in, bolt the seats in... and it should be driveable! Hopefully this weekend.



I also picked up a set of 37x12. 50 BFG Baja TA's on 24 bolt paired spacing HMMWV double beadlocks. I gotta re center them first though.



I got a detroit for the rear, and I still need to put the 4. 56's in the front.
 
Haha I've been very impatiently mad to not have time to work on it. The dang race truck takes up all my time! Then I had a friend blow up his 05 cummins, so I had to pull it, rebuild it, throw it back in... and it turned into one of those every dumb thing that can happen will type of jobs. Even the rail pressure sensor "went bad" somehow in the process!!



On to the front suspension... ..... drumroll..... nothing yet! I put the 64" chevy leafs in the rear, and with the stock shackle length it seemed to have about 2. 5-3" of lift. But by the time I put the top, fuel tank etc on that bad boy... Im down to about 1" in the rear. So right now its fairly level. Im hoping to now clear the 37's I bought for it with a ~1-2" lift. :)



For the time being, I want to get it running and driving with stock-ish tires on it. To do crossover steering I will need some lift, and I think Ive decided to just do coils and forget the idea of leafs. I think I would be happier in the long run. I have yet to measure to see if a 3rd gen coil will fit between the frame and the knuckle on the 1st gen frame/dana 60. If it wont, I might have to go back to the drawing board. I'd prefer to stay away from coil overs, but just might have to go that route.



My kids/wife have just been really, really, really wanting to ride in it. So I figure I'll get it running, start knocking out the little gremlins/details and get it reliable, then tackle the front suspension.
 
Nice. I've been wanting to convert to coils on my next project. I've got a '90 short bed that's gonna breathe fire, provided I ever get the time!!:D I'm planning on doing a coil spring on it, and I don't see any reason why they won't fit. The frame's narrower than the newer trucks, but the axle is close to the same width..... Building upper perches to take the rebounds is my biggest concern at the moment..... :cool: I'm afraid the 1/2 ton frame won't take the punishment I want to give it.....
 
The first gen axles are a little bit narrower, and the frame is a little bit wider. BUT... 3rd gen trucks use deep backspace wheels, so I think that makes up for the difference, or at least a good portion of it. I *think* I can make a 2nd/3rd gen coil fit in there. Using stock 3rd gen coil buckets and some bracing is probably the easiest way, and you can do a shock tower brace from tower to tower to help stiffen up the entire assembly.



I guess we will find out eventually. I cant say shortly... cause its probably one of my last concerns at the moment!
 
Bringing this back from the dead...

We moved a few months back and I never brought the RC over to the new house. But last night I did! So progress will resume shortly. I hope to have it at least driveable by June.
 
It's 'bout time!!! I've been wondering what's been going on with this...

Lookin forward to checking back tomorrow and seeing what you've got done! :)

Yeah... What he said :-laf





I can't wait to hear how it RIDES, considering you took a 1 ton truck and shortened it's wheelbase similar to a yard "switcher" for moving trailers around.

It shouldnt ride terrible. The rear is SOFT now with the 64" leaves. I used stock 1/2 ton leaves and yanked the overload, the softest 64's on a stock truck.

I didnt get much done this weekend... decided to go to the lake and romp on the 04 instead. I did get the RC running again last night, hasn't ran in quite a while now.

Heres a few pics of its new home tho...

I was hopin to drive it this weekend... but didnt get quite that far. I realized that I still needed to do some body mount work, and clean up some of the wiring. So I pulled the wiring harness back out to do some trimming and stuff. I also need to clean up the hole in the firewall for the HVAC box.

Gettin closer tho...
 
How 'bout an update... like a video skipping over some whoops or somethin :)

--Eric

Lol...I never saw your post Eric. Ill post some pics in a few days. No whoop skippin vids...but progress. Unfortunately not as much as I wanted, but progress nonetheless.

You move about as fast on your projects as I do on mine I think! Looking forward to it...
 
I guess I kinda forgot about this thread! I had acquired/started/completed a few vehicle projects in the meantime, for some reason the RC sat in the shop right in the middle but I couldn't find the motivation. This past memorial weekend we had no plans for once. We decided to avoid the lake due to crowds, avoid the desert due to it being hot out, and avoid anything that required leaving the house. It was a 4 day weekend for me, so Thursday night I decided I would see what I could get done on the RC. Every year we go to Silverton, CO in July for ~10-12 days and run trails, cook a lot of bacon and camp. I had bought a suzuki samurai the year before and hated the little POS, so that was some motivation to get the RC useable. So after 4 days of thrashing on the RC, I had it driveable in front wheel drive. I lacked building the rear driveshaft, rear brakes, back seats, rear shocks, and a bunch of little odds and ends. That left me with about 4 weeks worth of evenings to get it "trail worthy", with no weekends because it was Lake Season. I bought a set of weld wheels in the parking lot at work from a guy for 200$ for all 5, with decent tires. I picked up a borgeson double u joint shaft for like 100$ off amazon.

In the few evenings I had, I knocked out little things like getting the dash from the 93 swapped into the 79 tub, finishing body mounts, re mounting the 64" rear leaves because I didn't like the way they came out the first time, realizing that my new mounts are now in the way of the middle body mount, etc. After I was ~90% of the way to it being reality that it was actually going to make it to Silverton this year, I sold the samurai to give me even more motivation.

Long story short, we planned to leave on a Thursday night. The previous monday (4 days earlier), I still had not built a driveshaft, mounted the rear seats/seat belts, finished the exhaust or mounted rear shocks. I worked on it every night that week, finishing the rear driveshaft about 6pm on Thursday night (got it true to within .005" on the first try, zero vibes). I drove it around the block and to sonic. With about 3 miles on it, I stared at it in the shop wondering what I could do productive with my remaining few hours. I saw a gallon of grey paint on the shelf that I had bought at tractor supply for 5$...decided productive was unnecessary and I love to paint. I gave all the kids some sand paper told them to have at it. while they sanded I masked a few things and mixed some paint in the gun. 45 minutes later, it was painted grey. Definitely not a great paint job, buts its all 1 color. It will get totally sanded and repainted. With the paint still wet, I loaded it on the trailer.

We left at 6 the next morning and headed to Colorado with a box of parts, tools and bacon. After I got the motorhome all setup, I finished installing the seat belts and other little odds and ends. I hadn't quite got the rear lights figured out, the fuel sending unit did not work, and I had totally spaced windshield wipers. Oh well...I'd have to make due. I grabbed some friends and took the top off and went for a little ~10 miles trail jaunt that night just to make sure I wouldn't ruin everyone's fun the next day. There were ~40 people with us, mostly in UTV's and jeeps. We had friends and family with us from Louisiana to Phoenix, bust mostly from the Albuquerque area.

The first day we did a ~half day trail close to camp. About an hour into the trail, antifreeze began pouring down the firewall inside. Figured I popped a heater core. Opened the hood, nope...had a heater hose blow off! It was missing a clamp. First problem, easy fix. Filled er back up with Rocky Mountain Stream Water. The brakes began to get a little squishy, but I had expected that as I had bled them once, with all new parts and figured there had to be some air left in there. At the top of the trail I looked and one of my new rear brake lines was leaking, but I had spares and a flaring tool back at camp. Ended up just being a little loose at the junction block below the master cylinder, easy fix #2. As the day went on, the rear developed a clunk. I figured it was a shackle/leaf spring bolt, or perhaps the muffler banging on the crossmember. Well, the 20 yr old POS rancho 9000 shocks had dry rotted bushings, that evicted themselves. I made some new ones out of heater hose and fuel hose back at camp, easy fix #3.

Day #2, we did a long trail to Lake City. I put a 3rd row seat in the RC with 4 seat belts (kid sized), and a few friends that came brought their rock crawlers on Stickies, and they hate driving them on pavement. So I had 10 people (5 adults and 5 kids) in the RC that day. It performed flawlessly. I hadn't even had to lock the hubs in yet. By the end of the day, my homemade shock bushings had gotten a little loose but that was the only issue all day. I ended up making new bushings every morning, and that was the only maintenance it required the remaining 8 days.

In the end, over 10 days I put 417 miles on the RC, ~400+ of it was dirt, and those were the only issues it had. I have about 1K miles on it now. The rear springs have settled a bit like I expected, but other than that, its a ton of fun to drive. I still haven't fixed the fuel sending unit, wipers, or put a back bumper on it. Next on the agenda is suspension. I am 10000% pleased with how the 64's ride in the rear. Ill throw some rezzie sway-a-ways I have back there, or perhaps some new 7100's. I am still torn between some ORD spec Alcans, 52" rears up front, or just radius arms and coils. Every day something changes my mind. Right now, I'm in the radius arm/thuren coil/smooth body shock mindset. Tomorrow it will be 4 link and coil overs. Who knows where it will end up...but I have a new set of 37's waiting to go on.

The way it sits right now, it has a dana 60 front/14 bolt rear with 4.56's. I shaved the rear 14b for clearance. Now that I have a full fledged purpose built rock crawler, the RC's purpose is more do it all. I don't want to go taller than 37's. I want to keep it low (~4-5"), trim fenders, make it ride nice, flex ok, and work as good as my 3rd gen in the whoops. Power wise, the Don Morrison/Joe Donnely injectors, pump mods, hx35/14cm wg, and banks intercooler is a great combo. With the little 32's and 4.56's it will roast the tires just before the shift into 3rd, but it doesn't like to go much faster than about 70 before it feels like I am abusing it. The 37's will fix that. The seating for 10 is super cool. 4 kids fit great in the 3rd row bench (stolen from a 2nd gen quad cab). Behind the 3rd bench I have 2 tuffy boxes full of tools and spare parts, with enough room between them for oil/antifreeze/etc.

Still on the list; Paint/bedliner, suspension, bumpers, lights.

A few pics I have:
Pretty much where I started memorial weekend. No dash, most of the suspension mounts just tacked in, no body mounts, no exhaust, wrong perches on the rear axle, no brakes, no steering, etc.

And a little tribute Picture. My grandpa (Chuck Peeples) was an avid Diesel/Cummins enthusiast his whole life. He was a TDR member for a long long time. He passed away in 2011. We spread his ashes on top of Kendall Mountain in Silverton. He was a trail guide up in the San Juans and took me up there every summer as a kid. Hes the reason we still go up there every summer. This picture is the Cummins RC parked where we spread his ashes, I'm sure he was smilin'.

That's it for now. Ill try to remember to update this as I make changes/upgrades.

P.S. For those of you wondering, the spare tire stayed on the tailgate with ratchet straps the entire 10 days without flaw. It outlasted numerous sets of shock bushings. :)

Not much of an update. Workin on getting the 37's to clear. I've been messing with backspacing and such. I would like to end up with ~6" bump travel and 4" lift, which means I need to raise the factory bumpstops and check clearances. I'll probably do some trimming, pull out 2 leafs, raise the bumps and see what it's gonna take to get clearance there.
