This Fabtech K1136 / K1136M 4 inch lift kit for the Chevy Silverado 1500 Trail Boss adds to the factory 2 inch lift for clearance to fit up to 35 inch tires. This kit features all required components like heavy duty 1/4″ thick steel crossmembers that use OE style alignment cam pins that utilize the factory cams for easy adjustment. Triple front diff mounts reposition the differential for vibration free operation at high speed. The near stock track width keeps the tires under the fenders for a clean appearance. Fabtech’s proprietary steering knuckle geometry provides excellent lock to lock turning radius to maneuver in tight spots. The factory Trail Boss and AT4 coilover shocks are retained and relocated from the bottom to allow for full steer while achieving 4″ of lift.
Rear lift is accomplished by removing the factory 2″ block and replacing it with a 5″ block and u-bolt system.
