Skyjacker C140BKS-B 4 in. Suspension Lift Kit with Black MAX Shocks

The Skyjacker C140BKS-B is a complete 4-inch suspension lift kit engineered for GM 3/4-ton trucks equipped with 52-inch rear springs. Designed for use on 4WD applications, this kit delivers a significant lift while preserving the smooth, controlled ride quality drivers expect from the factory — both on daily roads and off-road terrain.

This system pairs Skyjacker's proven Softride leaf springs with their Black MAX shock absorbers, a purpose-matched combination that balances lift height with ride comfort and load-handling capability. The Black MAX shocks are velocity-sensitive, providing firmer damping under aggressive driving while remaining comfortable during everyday use.
