Engineered Twin-Tube Control for Demanding Terrain
The Skyjacker Black Max shock absorber B8574 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 2002-2005 GMC Yukon XL 2500 4 Wheel Drive w/ Rear STD Suspension. 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.
