im starting to think i should just save up and get the totalchaos bal joint caddy kit.
That might be your best bet. I did the whole ball joint spacer thing with mine, and honestly, I wouldn't do it again. Don't get me wrong. The parts were of good quality and worked as advertised but in the end all the new travel is droop travel. Frankly, droop travel isn't very useful. The hanging tire isn't doing you any good in a 4 wheeling situation anyways. If it is hanging 2 inches off the ground or 1/2 inch off the ground is really irrelevant.
Of course me being me, the BJ spacers purchased in a group buy bargain at $88 led to a much larger project. You know, "as long as I'm in there" might as well get new ball joints, and tie rod ends, and control arm bushings, and shocks, and a steering dampener, and a rear truss, and an idler arm truss, and rebuild the idler arm... Turned into a several hundred dollar project and while it worked OK, I don't think in hindsight it was worth the time, money, or effort. You can get 33's in there as is if you desire which will do more for ground clearance than anything else but will likely make you desire a regear of the diffs. If I had it to do over again I'd stick with 31's and get locked and armored. Rear locker has been by far the best mod I've ever done.
I had a Downey rear truss but they are now out of business. Sonoran Steel makes a beauty that was not available yet when I got my Downey, otherwise that is what I would have had. I don't know if anyone else is making them now with Downey out of the game. My Downey ended up looking like this but Sonorans is much beefier. Still, it did it's job.
