It's pretty hard to beat the JBA for the price, they use chevy ball joint and are easy to change out. I have the SPC's, They keep getting knocked out of alignment. If I was do to it all over again, I'd get the Icon delta joints.

Stay away from the 5100/OME lift kits. Mine sucked, I replaced it with new coil overs after they failed at less than 10K miles. The 6112 is a much better kit IMHO.
