========= Original post below =========

I own a 75 Wagoneer (since '97) and a 01 TJ. The TJ I bought new in 2000 and used as a daily driver for the first three years. During that time I ran a 3" lift and 31s ATs for street driving and 33 Swampers for offroad. In this config I ran stock gears and put a lock right in front. In around 02 I put in an Atlas II 4.3 to help out my crawl while keeping my highway gears since it was still a DD.

In 2002 I put on a 5.5" RE LA and moved to 35" MTRs. I regeared to 4.56s and put a detroit in the rear to replace the blown out trac-loc. After a few trips wondering if I could make it home, I decided it was time get a truck and trailer, so I took advantage of the 0% interest at the time and bought a Chevy 2500HD.

I started looking into putting a d44 in front, then found a good deal on a d60 for the rear. Then I found a great deal on d60 front so a whole new project started that ended up with me running 39.5" Iroks on 15x10 allied beadlocks. I was still running the RE LA, but we reconfigured the rear to be a 4-link.

The front d60 was shortened to 64.5" WMS to WMS and converted to 5x5.5 to work with the beadlocks I got for a good deal used. It got Moser inners and, 4.88s and detroit. I started with stock steering, but snapped the pitman arm after a year and moved to full hydro. The rear d60 was converted from FF to SF with 4.88s, spool, and 40-spline moser shafts.

Around the time I went to full hydro, I scrapped the RE LA and re-did the suspension. The front is 3-link with a panhard and the rear is a 4-link. When building it we stretched the front 8" and the rear 4" for a wheelbase of about 106".

We recently put in the cage. I kept setting up to have it done, and it would fall through for one reason or another. We finally bought a bender and just did it.
