Installed the Currie rear springs,rear trackbar bracket, and rear shocks/ brackets this weekend. What a PITA, really poor instructions. Zero tolerance, and had to ream out most holes in brackets to fit bolts through them, let alone getting bolts through axle brackets. One rear Rancho RSX 9ooo shock had eurothane bushings, other had silica (major pain fitting bar pin in that one)(should have got bpe's i geuss).Instructions for rear bumpstops say"drill and tap 7/16-14" Someone could drill 7/16 making hole too big. Should say drill like 3/8, then tap 7/16, or something like that. Also those bumpstops are pretty, but a pain to get in, need 4 hands. Have yet to do front. Going from a 3 inch lift to 4, have some vibes around 25mph. An SYE/ shaft at christmas time will be tricky.
