I figured id reply in here in regards to your stretch q's. ive been researching the rear stretch as well and what ive seen a couple guys do is get the ruff stuff "way-back" spring hangers and mount them on the rear crossmember. In conjuntion to this, you can keep the original spring hangers on the front (frame-mounted) and use XJ springs, or else you can cut off the original frame side spring mounts and move them towards the rear and reweld them. The latter seems to be the cheaper route. The downside is it puts your WB around 105-106" which i think is a bit long for 35s.
On pirate there is a writeup on how to dimple your gastank if you dont want to run a fuel cell. Ive heard the fuel cells let off fumes that can gas out you and your jeep. Also ive heard word of using a Camaro gas tank, but im not sure if anyone actually did.
Personally im kinda diggin the idea of a 4link. Fully adjustable, more stability, flex, and ride comfort. Takes alot more research and elbow grease but oh man would the fruits of that labor be dope!
Yea. i've been doing A LOT of research those past couple days about this. Here's the thing... I have what are basically brand new 35s (only put about 500 miles on them. 2 wheeling trips). I probably wont be going bigger for a couple yrs if i can stay disciplined. That means that the wheel base can't go over 100" really (for now). Stock WB is what... like.. 94". i figure 5 inches in the rear and maybe 1 inch in the front if i even feel like it (i'm more interested in rear stability to climb steeper obstacles. at least for now). I really wanna keep this project to a minimum $$wise. i can use my current SUA setup/leafs and just move the hangers AND shackle mounts 5 inches rearward. That would allow me to use my current springs which are barely broken in.
I wouldnt be welding those shackle mounts onto the weak crossmember tho. I'd be cutting that off and replacing it with either some 1x4x3/16 or 2x4x3/16 or even some 3/16" plate..
Anyways, i figure I could do this project this way for very cheap. $200-300 max. I already have long SS brake lines. I can easily relocate the shock mounts. Re-shape/Re-locate the tank. All id have to do is lengthen my rear Driveshaft and buy the metal/mounts
I may be forgetting a thing here or there but essentially its really all that's involved for a mild stretch. I'm trying to put all of this together and gather everything i need before i tackle this. But i feel it can be done relatively quick if all goes well. What do you think about the plan?
As far as 4-link, that's something i could see myself doing in the future but not right now. The 5" stretch in the rear definitely wouldnt hurt.
Edit: I could actually sell my current GenRite bumper plate to recover most of the project's cost. Right brand new.
