Repairing, restoring or modifying your ride just got a whole lot easier!

'86 Jimmy 39.5 TSL's 4in lift a.k.a. Jimmy Truck-8.1 Swap…Right back at it again!!!

This is not a dedicated trail rig, but does trailer to the destination usually. I am currently in the planning phase of doing a 52/56" spring swap, and getting back to being more road worthy.

GWeakland620 submitted a new Build:

86 jimmy 38.5 4in lift a.k.a. Big jim

Ok, first things first, this thread will be a slow starter. I do not spend alot of time on the computer outside of work, and most of my pictures are at home or on camaras (that i do not have access to at work). But I have a few here to get started.

Here we go,

I found this truck on C-list for $600 obo. Said it ran and drove in 1st gear, but no higher gears. Went and picked it up on a friday night after work for $300. Got the truck home and started to dig in.

The truck I found out was rust free from AZ and had 108k miles on it. It had been sitting since 05' and was in need of some TLC.

I started by swapping in a newer Jegs crate 350 and a built 700R4 that were from an old project i had.

Shortly after that I had a pair of 10bolt axles out of the same truck as the doner eng/trans/t-case, that had 4.56 gears in them and 36x13.50R15 Iroks on them that I swapped in under the Jimmy.

The next step was a fresh coat of high-quality rattle can flat black. Followed by some rally wheels and smaller but better shoes. Some 35x12.50R15 KM2's to get a little more grip.

Also, somewhere in all the swapping of tires and axles, I did the ORD shackle flip kit to get rid of some 4in blocks the got put on with the doner 1/2 axles.

Went to Randolph ORV park with some buddies and played around for a little bit. Shortly after that trip, I decided that I wanted to got bigger and better, cause who really doesn't? So I started hunting for 3/4 tons and bigger rubber.

So a friend of a friend had a good "starter kit" for my search. 14bff with 4.56 gears open diff, and 9 military Wrangler OZ's with a set (4 wheels) of recentered H1 double bead locks with rebar reinforced wheel lips.

Got all 9 tires with the set of wheels and the rear axle for $1150. Sold 4 of the tires for $200 to my brother and kept 5 of them.

The axle I got home and got to workin on it. Stripped the drum brakes off of it and swapped on a disc brake set up. Went with Ruff Stuff for the brackets.

Nice:waytogo: the Humvee tires are hard to beat for the money. Especially if you do much street driving. They wear like steel and still work pretty darn good offroad once you air them down. Great build:thumb:

Thanks sir. I ran those military tires for about 5-6 runs and I did like them alot in the rocks. As for the mud, they were not my best friend. And when I introduced any moisture to the rocks they were not very good as well. If I ever built a multi-purpose/DD I would run those in a heartbeat though, they DO wear like iron/steel and run down the road fairly straight and aren't too bouncy. But as you'll see later in the build, I found a tire deal I couldn't pass up :D

So, back to the build. After I picked up the 14bff I came across a dana 44 with 4.56 gears and an open diff for $125. Took it home and began to tear into it as well. For starters I got a Reid Racing knuckle for the pass side for my future cross over steering, then went through the axle and checked all the seals.

I was then ready to mount the 37's on the H1's and get some rolling axles.

A week later I got the truck over to 83SuperBurb's shop to start tearing into the Jimmy and setting it on some 3/4 tons and 37's. For now I was going to leave it with the factory steering style with the 4in lift steering arm.

The next weekend I took the Jimmy out to do some clearance testing. I had to trim a little but not as much as I thought. Also forgot to add, when I did the 3/4 ton swap I added a set of ORD's 9000 shocks, 10in travel front and 12in travel rear.

Next it was time to address and issue we all know and love, the cracked frame behind the gearbox. I do apologize in advance, my dad ended up finishing the weld-in frame patch without me being able to document much. I still am in need of the bolt-in brace, so I will post some pictures when I get around to that.

I have a before and after but no during. Pictures are on wifes camera and can't access them right now, but I will post them. I did have 1 small "stubby" issue while on the first run........:doah:

Next I pulled the truck apart to fix the stub shaft. Went OE with the shaft and the u-joint due to $$$. It was then time for bumper delete and a real nice trim job :waytogo:

And yes, my friends are homo photo bombers:dunno:
