Skyjacker Black Max Shock Absorber 1987-1987 GMC V3500 Pickup

Engineered Twin-Tube Control for Demanding Terrain

The Skyjacker Black Max shock absorber B8578 delivers vehicle-specific, multi-stage StableSteer valving built around a twin-tube, foam-cell design for consistent damping across street driving, towing, and off-road use. A chrome-plated shaft and sintered iron piston resist wear and pitting, while 360 degree arc-welded end mounts and 180 degree directional mounting simplify installation on 1987-1987 GMC V3500 Pickup. Increased fluid capacity improves heat dissipation during extended or heavy-duty use, and each unit ships with a protective black boot to guard the shaft from debris.
