tj stretch q's

Looking to stretch the rear of my tj. Right now I have 4.5 re long arm kit. When looking at other builds it seams like everyone either moves everything back on the stock frame, or they cut the frame right before the rear wheel well and make it straight. Has anyone ever cut right before the frame starts to angle up and added in 4-5 inches of frame? That would allow me to keep all the same mounts and just move back the re arms. Any input?

If I read that right...are you talking about making more angle in the shocks to move the axle back and lengthening your control arms

No, seeing if anyone has added 4-5 inches of metel and welded it in right in front of the wheel wells. instead of cutting the back half of the frame off like this go about half way down the page

Sure, quite a few have done it. It ends up being about the same amount of work, as you still have to hack the rear frame and fab up a rear crossmember and bodymounts.

The RE arms attach to the crossmember. You'll need to either lengthen the arms (not good) or fab new mounts. Either way, it's quite an undertaking in any regard. Be prepared.

you move the axle back to improve departure angle rite? by adding in middle you are just making a longer tj,

If you are only adding 4-5" you do not need to add to the frame.

IMHO, >4" and you should add to the frame. After that, the rear coils either get awful short or the fronts get long.

If you are going through that much work to stretch it, go to at least 100" WB. I would stretch at the arch, and leave enough room to move the buckets further in the future if needed. Ask how I know

Mine is 5" with the coils relocated. Uses the same lift spring size front and rear. Fuel tank removed, fuel cell between the frame.

Sure looks like one...




And here is his "redneck soft top solution"...





I would think simply finding an LJ would be an easier solution; but considering what he already had invested in this rig, I can understand why he did it!

What the OP is wanting to do, is probably NOT purchase an LJ.
The LJ has too much tub behind the rear tires. I also have a TJ, and am seriously considering extending the
rear axle rearward. The improved the rear departure angle. But the main goal of lengthening the wheelbase is a better tiresize/wheelbase ratio. You can run 37's on a TJ, but adding a few inches of wheelbase will make things dramatically more stable.
Plus, adding wheelbase to the shorter TJ body makes your rig more nimble.
But like stated, it's a pile of work. You can do the GenRight gas tank, but it's $$.
Some people run a fuel cell in the rear behind the rear set. But if you're looking at chopping up the back half of your TJ, you're too the point of not running a back seat.

My plan is to stretch the front first. Then maybe next year stretch the rear. Gaining wheelbase @ the front is WAY cheaper/simpler than the rear.

I wouldn't bash this guys soft-top too quickly. This rig is obviously not daily driven, thus no need for a super-nice soft top. It's a good attempt at a soft top that is probably rarely used, if at all.
BTW; that's a pretty damn nice rig.
