Rancho RS9000XL 4″ Lift Shocks for 2007-2013 Chevy Silverado 1500 / Yukon

Part Number: RS999786 / RS994297

Summary: The Rancho RS9000XL series provides industry-leading adjustability for owners of lifted GM trucks and SUVs. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for towing or aggressive off-road use. Specifically configured for 4-inch lift heights, these shocks ensure your vehicle maintains proper suspension travel and control after a significant increase in ride height.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure the driver can tune the ride for daily commuting, heavy hauling, or trail performance.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent cooling and reduced fade during high-temp operation.
• Nitrogen Gas Charging: Pressurized gas displacement provides a reduction in aeration and foaming to ensure immediate response and consistent damping control.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier against debris to ensure the piston rod and oil seal remain free from damage.

• Engineering Advantage: Rancho’s MyRide technology allows for a massive 400% damping range, making this one of the most versatile shock absorbers on the market.
