The Skyjacker 2.5" lift kit for the Jeep Wrangler YJ includes both front and rear Softride leaf springs with bushings and u-bolts. No steering correction is required with the Jeep Wrangler YJ lift kit. Skyjacker hydro shocks sold separately. The Softride springs manufactured by Skyjacker use tapered leaves to yield a lower spring rate and better travel, Teflon wear pads to help reduce interleaf friction, a "bolt" style clip to reduce leaf friction and shot-peening to compress the steel and increase its tensile strength.
