Superlift springs

[chazgin]

Bought a fiberglass body 84 CJ for rebuilding with parts from my 85 that has a rotten tub. This CJ has an auto trans that I plan on swapping with a Ford T18 (see different thread). The guy that I bought the 84 from said " Oh here take these I'm out of playing with CJ's". The these is a Superlift full lift kit. I looked it up on the Superlift web site and the fronts are PN# 530F = 2.5" lift and the rears are 529R = 1" lift. Inthe paperwork I found a bill of sale from the store that sold this kit (back in 1999) so he recieved it that way. What is up with the 2 different heights? I plan on running 255/85 R 16's on this vehicle with full chains (when required) during hunting season so need clearance for the chains. Is the kit correct or do I need to get both springs the same height. If so which height 1" or 2.5" ?
