Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications and lifted setups. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying payloads or terrain. This Tier 2 adjustable technology provides the perfect solution for Silverado 1500HD and Hummer H2 owners who require a soft ride for daily commuting and firm control for towing or off-road excursions.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the vehicle is perfectly tuned for street, towing, or trail use.
• Large Diameter Shock Body: The 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during long-distance hauling.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a rapid response rate to ensure consistent tire-to-road contact on uneven surfaces.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
