Skyjacker 4.5-inch lift system for Jeep XJ/MJ applications pairs Softride rear leaf springs with Black Max shocks to increase ride height and axle articulation. Softride springs are shot-peened and tapered to distribute loads and enhance travel without sacrificing spring life; they use bolt-style clips to reduce friction. The system is constructed from American steel, offers load capacity equal or greater than OE, and a limited lifetime warranty applies.
