- DESIGNED FOR HARDWORKING VEHICLES -- Ideal for stock or lifted trucks, SUVs and Jeeps that tow, haul or go off road
- INDUSTRY FIRST -- Recognized as the first nine-position manually adjustable shock series in the off-road market
- REDUCES FADE -- Nitrogen gas pressurized to 120 PSI to minimize air-to-oil mixture and reduce damping performance fade and foaming
- STRONG AND DURABLE -- Features an application-specific 18mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas and 1.25-in. sintered iron piston for enhanced structural integrity
- HANDLES EXTREME TEMPERATURE CHANGES -- Up to 2.75-in. tri-tube body (application specific) filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248°F
- SMOOTH PERFORMANCE -- Polyurethane rebound bumper and bushings and graphite-filled fluon-banded piston help absorb ride harshness and enhance responsiveness to changing road conditions for an overall smoother ride
- BUILT TO LAST -- Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the long-lasting premium liquid metallic finish and polyvinyl protective boot ensures longer life
