    Skyjacker's Black MAX Shocks are a twin tube shock absorber with increased fluid capacity and utilizes 'foam-cell' technology. This foam-cell technology compresses to compensate for oil expansion when the shock is hard at work and is hot. These shocks can be mounted in any direction due to the foam-cell technology eliminating air pockets within the shock tube. Features arc welded end mounts and specific select valving, giving these shocks an edge over the competition.

    Features:
  • Twin Tube Construction.
  • Advanced Foam-Cell Technology.
  • Increased Fluid Capacity.
  • 180° Directional Mounting.
  • Arc-Welded End Mounts.
  • Vehicle Specific Select Valving.
  • Fits Specific Lift Ranges per Application.
  • Includes Black Boot.
  • Sold Individually.
