Complete 2.5 Inch Lift Confidence For Your YJ
The Skyjacker YJ21BKB is a complete 2.5 inch suspension lift kit built for 1987-1996 Jeep Wrangler YJ owners who want a ready to install system rather than piecing together individual components. This kit pairs Skyjacker's tapered lift blocks with front and rear leaf springs, U-bolt kits, a bushing kit, and four Black MAX shocks to deliver a balanced ride on the street and confident control on the trail. Black MAX shocks use a valving designed to control body motion without the harsh, jarring feel some aftermarket shocks introduce. Because the YJ21BKB includes every major component needed for a 2.5 inch lift, installation is more predictable and the finished ride height and geometry are dialed in as intended by the manufacturer.

- Includes 4 Black MAX shock absorbers
