has anyone thought of and tried to make a six wheel drive jeep out of a pickup? iam thinking about doing this on a future project after the one iam working on is done.

COOL FIRE_DRAGON...I haven't seen it in an FSJ yet. I hope you do it. I've got a photo of a VERY unusal one in Silverton Co. I can't post it but would e-mail it if you like..... :cool: ...ds..

Dodge did it with the T-Rex concept truck a few years back, real cool.

Hey don, would you e-mail me that pic? I always like the oddball stuff :D

fire_dragon61 03-30-2002 10:42 PM

please do send the pic please. that where i got the idea from was the dodge t-rex since they did not put it into production would have liked one. thought i could get a axle set up off of a old military duece and a half or five ton.

its been done a few times, sometimes even without special axles! Never seen one done to a fsj, but fourwheeler and others have shown multiple versions, there was a (i think) m151, cheby, an old cj (i think)

To do it without the axles with 2 pinions, the usual M.O. is to take a divorced tcase, slap it in behind the main tcase, w/ the main tcase driving the front output, leaving you with 2 outputs pointing back, then you run an offset and a centered rear axle, and pray you dont smack your driveshafts

I can see a lot of advantages as well as disadvantages with that setup. Articulation would be key to the success of the two driveaxles. I drive truck and have hung the forward axle in the air by dropping off a high curb or other uneven ground. then with the rear axle in mud or snow usualy end up needing a pull. Another disadvantage is more axles to the ground the less the PSI, to much weight distributed onto more axles = less traction. This was proven in Semi trucks I drove in the Mountains. We had several test trucks that were tandem axle but only one axle was live. When we would go through the mountains or ice covered roads the tag axle was lifted thus leaving only the drive axle of the tractor on the ground. The differance between this system and the conventional tandem axle with Diff locks was night and day. I begged to keep the test truck, I never had to chain up as often as I did with the live tandems. I doubt I would ever mod a FSJ to a 6 X 6 but it sure does look cool. Here is a nice pic of it.
6 X 6 .........YUCK....... A DODGE!!!!!!!!!! :D :D

hmmmm never had a problem getting stuck when i was in the military driving duece and a halfs and five tons. of course i didnt get my tank stuck either!! lol thats why i thought that system would work the best.

Crazy_Jeepman 03-31-2002 07:32 AM

I beleive the military duece and a halfs and five tons utilized a walking beam system under the single spring. I have Driven semi's with the walking beam system it fairs a lot better than the air ride or the Hendrickson Spring suspension. Not to say that the Dodge T-Rex concept truck has any problem with the axles articulating, however it should be a concern. Still the fact remains more tire on the road less the traction. Ever notice how a Dual wheel pickup is about as usless as all get out compared to a single wheel, and with out weight in it, YIKES ;)

I remember seeing a 6x6 CJ8 in one of the Peterson mags about four years ago. I don't know if a search on one of their sites could get anything. funny thing, if I remember right, the back diffs each had their own shaft coming from the t case.

cool cj,s but i would like to try it with a fsj.

You might steal some ideas from this

The running gear on it looks good, i've looked at it in person.

fire_dragon61 04-01-2002 05:21 AM

looks like it has alot of flexability over rough terrain has posibilities. but first i have to finish one project before i start another. i have two going on now lol dont think i can handle a third no room in the garage!!
