Rough Country Performance 2.2 Series Shocks
you need to call Rough Crap and ask them what the COLLAPSED length of the shocks are.
in the front:
13.5" collapsed length is the MAX that fits in the stock location with no bumpstop extension.
14.5" would require 1" bumpstop extension.
15.5" would require 2" bumpstop extension.
...you get the trend.
in the rear:
13" requires ~1" bumpstop extension.
14" requires ~2" bumpstop extension.
and so forth.
in the rear the bumpstop requirement changes drastically with lift height and CV shafts due to pinion rotation...so YOU need figure it out for YOUR rig...those numbers are just guidelines. and to figure these things out you need to pull your springs...or better yet do it while you install the lift and the springs are out!
