The Skyjacker Black Max B8573 is a twin tube shock absorber for the Chevrolet Blazer, GMC Jimmy, K15/K1500 Pickup and other vehicles listed in the fitment table. A foam-cell insert compresses as the oil heats and expands, keeping damping consistent across the shock's operating temperature range, and it can be mounted in any direction.
Black MAX twin tube shock absorbers have increased fluid capacity and utilize foam-cell technology. When the shock is working hard and gets hot, the foam-cell insert compresses to compensate for oil expansion which maintains consistent MAX performance throughout the operating temperature range of the shock. The foam-cell design also eliminates air inside the shock which allows for mounting in any direction. Arc-welded end mounts and select specific valving give this shock absorber MAX value.
