Extended Wheelbase

What would you consider the pros and cons of extending the wheelbase on a cj5?
Thanks Miles

Re: Extended Wheelbase

well if you are asking me you are asking the right person. i've done it. i cut my jeep in half and lengthened it to a 100" wheelbase. here you go

pro's
stabilitly, more room (depending on how you lengthen it), better on hills, better on climbing ledges, did i mention it is alot more stable!? longer rear d/shaft. more room for mufflers, track bars etc under there, etc.

con's
not as small of a turning radius, more sheet metal to ding (depending on how you do it).

i love my 100" wheelbase ALOT more than i did the stock one. it is alot more capable and less roll happy ( i sya that but i only layed it over when it was stock and i have rolled it completely since i have lengthened it). if i had it to do over io wouldn't lengthen the body but rather cut the rear of the back fenders out and slide the rear back. why? well like i saidd i have more sheet metal to ding and now with a rolled body i would have to buy another tub and then cut and lengthen it and i'm just not going to do it. i will run it like it is until i decide to build something else. this might not be an issue for youe if you don't wheel hard like i do. if you are just looking for more room the cut and lengthening is a good thing.

Re: Extended Wheelbase

What Brian said on Pros & Cons

I used the stock length frame, moved the front axle forward 4.5" with Alcan 50" SOA springs and moved the rear axle 5" back with 1/4 ellip springs and 4 link. Its very stable with the longer wheelbase(93"), 7"lift and fullwidth fullsize axles.

Alot of the top ARCA guy are running about 94" to 96" wheelbase.

Re: Extended Wheelbase

Another con to add: Less brak eover angle. Might be a problem on hard trails unless you have some serious lift.

Re: Extended Wheelbase

true on the break over angle. i thought of that but when i actually went to typing i didn't add it to my list. i run 38.5 sx's and it isn't too bad and it actually wasn't too much of a problem with the 35's i used to run after i tucked the tranny/x-case up higher into the frame rails.

Re: Extended Wheelbase

Thanks for the help. 100" takes you right past a cj7 in wheelbase. Why not just start with one of those??
More info on those Alcon SOA springs and your 1/4 elliptical would be great. How stable is that set up at highway speeds??
Brian, where did you lengthen the tub?
Thanks Miles

Re: Extended Wheelbase

There is more on my suspension on my site, just click below, Its very stable on the highway with a little body roll in tight corners. It's the best setup I've used, so far.

BTW, Some wheelbase info,
