Skyjacker 1987-1987 Chevrolet V20 Pickup Black Max Shock Absorber

Twin Tube Damping Built for Chevrolet Trucks and SUVs That Work Every Day

The Skyjacker B8521 Black Max shock absorber replaces a tired factory or aftermarket shock with a twin tube unit built around foam cell technology, arc welded end mounts, and vehicle specific valving. It is designed as a direct bolt in replacement for stock ride height or mild lift applications, giving drivers predictable control whether the truck is empty, loaded, or towing.

Key Features

• Twin tube hydraulic design with advanced foam cell technology that compresses under heat to prevent oil aeration and fade
• Vehicle specific multi stage valving tuned for a controlled, stable ride
• 360 degree arc welded end mounts rated for extreme off road stress
• 180 degree directional mounting allowed by the foam cell design
• Chrome plated shaft resists pitting and corrosion
• Sintered iron piston for consistent damping over the life of the shock
• Black dust boot included to protect the shaft from debris
