Wrangler and Gladiator kits come in these, also some performance parts like engines. Four new coil springs, extended Fox racing shocks, longer front lower control arms to correct the caster angle, extended sway bar links, bumpstops, and assorted hardware. Box is basically a two foot cube of 3/4" BC plywood with pallet feet nailed and braced under it. It doesn't look like 3/4" from the front because all the edges are stepped so the panels lock together and are held by L-clips that latch into the grooves cut in the panels.
