Part Number: RS999118

Summary: The Rancho RS9000XL series delivers industry-leading versatility for drivers who demand total control over their vehicle’s damping profile. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy hauling or towing. Engineered to eliminate the compromise between comfort and performance, this nitrogen gas-pressurized shock is specifically configured for stock height (0″ lift) applications.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for any load or terrain.
• Large Shock Body: A massive 2.75-inch diameter body provides increased fluid capacity to ensure cooler operation and consistent damping during heavy-duty use.
• Nitrogen Gas Charged: Gas pressurization at 120 PSI provides a rapid response rate to ensure minimized aeration and foaming.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure longevity against road debris and corrosion.

Frequently Asked Questions

Do I need tools to adjust the shock settings?
No, the 9-position knob is designed for manual adjustment by hand, allowing you to change your ride quality in seconds without tools.

Will these shocks lift my GMC R3500?
No, these shocks are configured for vehicles at factory ride height (0″ lift) and do not provide lift on their own.

What is the benefit of the larger shock body?
The 2.75-inch body allows for more oil capacity, which helps dissipate heat faster and prevents performance fade during towing or long hauls.
