The information on this site is an OVERVIEW of how I installed components and made modifications to MY CJ but this in no way means it will work or be safe on yours. My CJ is built as a street legal (to drive to and from the trails) trail rig and the modification are to enhance TRAIL USE ONLY. If you DO NOT have a excellent working knowledge and background in machanics, DO NOT try these modifications.

(11-10-01)Again, haven't updated for a while so here it goes. Finished moving the rear axle back another 5" by adding long links to the four link suspension. Now the wheelbase is at 93", which is 1/2" less then a CJ-7. This was in part to deal with driveshaft angles, improve departure angle(85 degrees) and also improve climbing ability. After lifting the CJ higher, widening the track and lengthing the wheelbase, the overall stability is greatly improved.

I remove the fixed shackle mounts on the rear axle and made a shackle with a large Heim joint that mounts the axle. This allows for axle articulation without spring twist, relieving stress at the spring mounts. This will also extend the life of the springs by not working at compound tensions.

The custom Tierod setup is done, Which mounts the tierod behind the axle and above the springs buy using custom made steering arms. This along with the ARG Rock Ram Kit makes this one of best modifications I've made. The steering is nothing less then amazing, this system is unstopable.

Picked up a Tire Groover from AFCO and went to work on the SXs. BIG improvement in on and offroad traction.

Mounted a Warn MX 6000 to the back of PYRO with a custom made bumper. You can also see in this pic how far back the axle sets now, the back edge of the tire is even with the bumper!!!

(4-10-01)Today I received the papers for my entry in the Hawaii Top Truck Challenge !!!!!! I've got alot of work to do between now and July 1st, the challenge date. I'll be shipping PYRO to the Island of Oahu and meeting with a bunch of wheelers there. We have a few trail rides planned and then, over to the event at Kualoa Ranch. Should be alot of fun with some good hardcore competition.

I'm in the proccess of swapping in a SM465 w/Dana 300, short output and Tera 4 to 1 low Range . I'm also working on a "Home Built" Hydro Assist Steering and I'll do a "How To" writeup on it. Along with that I'm moving the tierod to the other side of the axle and over the springs, should be a very trick setup.

(2-08-01)Well, Its been a while , but I'm back at this page again. Been pretty busy working on PYRO lately and just about have the latest phase finished. I've added some axels, some BIG axels. The front is a Dana 60 out of a 1.25 ton chevy military truck and the rear is full floater 14 bolt from a chevy dually tow truck. When I flew over to pick up the axels on Oahu, the guy had a set of 37 x 12.5 MT Goodyear Military tires from a Humvee so I ended up buying those too. Now , to fit this all together I needed a new suspension so I called the guys at Avalanche Engineering and ordered some Alcan SOA springs for the front and Avalanche's 1/4 elliptical rear suspension kit. The links above go into more detail on these components and their installation.
