With all the suspension modifications that have taken place up to this point, there are a few on my list I'd like to do to clean things up. They may or may not be happening right away and there are a couple more modifications I'm contemplating at the same time.
With the current 5" lift, soon to be 6", there are some pretty significant angles on the differentials. I hate degree shims with a passion and these (6* in the rear) are really not making me happy. Here's what'll be happening over the next 3-4 weeks.
1 - Installing a 1-1/2" lift rear shackle (Teraflex). The XJ is notorious for a short OEM shackle and word has it this is the lift to get.
2 - Install a shackle re-locator (Rough Country). It also has a measured lift of 1" or so. After installation, the net lift will be determined and the front coils will get a spacer to equalize lift front and rear. I'm told not to expect more than ~1" net lift even thought the numbers might indicate otherwise ... with the proper operating angle and the shackles allowing more flex.
So, the operating angles of the differentials will be even more extreme. I've heard of cases where the the spring perches are cut off, the pinion angles adjusted and perches welded back on ... no more shims. Should I pursue this? Now for the additional work under consideration.
What about stretching the wheelbase? The XJ is 104" in stock trim and with lift something less. As it stands currently, my clearance to the transfer case crossmember (my lowest point) is about 21". I'd be looking to improve the attack and departure angles. I'm looking at moving the front axle about 1-1/2" using the adjustable CAs (Rough Country). The rear could include drilling the spring perch and using a "axle relocation plate" for up to 2" ... all welded to the axle for support. The shock mounts would be relocated at the same time. Should I pursue the stretch or let it wait?
Thanks!
