What do I have?2.5\" or 4\" ProComp lift?

I recently purchased a 93"YJ and I know it has a suspension lift but I'm not sure how big? I am looking into buying "swaybar disconnects" but I'm not sure what length I should buy so please HELP.... The only thing I can tell you is that I do run 33" BFG,on 15"x8" rims with extended "Zenon" flares and they do not rub. I have about 2" of clearance on the flares and the shocks are definitely "ProComp". It might have a shackle lift also, but I really can't tell.
If you need more info. ,please let me know.....Thanks

I think the easiest way to tell if you've got a 2.5" lift or a 4" lift would be the size of the spacers in the transfer case drop kit, assuming you have one. A 4" lift kit would have a 1.5" - 1.75" transfer case drop kit, or thereabouts, I think ,and a 2.5" lift kit would have a .5" to .75" drop, or thereabouts. The procomp 4" kit comes with cylindrical spacers for the drop, and I know some of the 2.5" kits come with a flat metal spacer with the 3 holes in it.

The stock shackles are stamped sheet metal, and I think are 3" or 4" in length, bolt center to bolt center. If you have something made out of flat steel plate in the 1/4" to 3/8" thick range, you've got aftermarket or homemade shackles.

Good luck

If your clearing 33s with no rub (at all, ever, wow!) then most likely you have the 4" lift kit. Park your Jeep next to a stock one and compare shackles. If your shackles are really long then you'd have handling problems.
