Product Description

The Skyjacker B8579 Black Max Rear Shock is a durable replacement shock designed for lifted full-size trucks and SUVs from the 1970s through the mid-2010s. Its twin-tube hydraulic design with foam-cell technology maintains consistent damping performance, preventing shock fade during heavy-duty on-road and off-road use. This rear shock is commonly installed with 2"-8" lift kits on Ford F-Series and classic Chevrolet or GMC 4WD trucks.

Engineered for longevity, the Black Max B8579 features increased fluid capacity, multi-stage valving, and arc-welded end mounts. The chrome-plated piston shaft and protective boot resist wear and corrosion, delivering reliable ride control under demanding conditions. Ideal for truck owners seeking enhanced rear suspension performance and stability with lifted setups.
