Part Number: RS999120

Summary: The Rancho RS9000XL series delivers industry-leading versatility for owners of the GMC R2500 looking to enhance ride quality and control. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from soft for daily commuting to firm for heavy towing or hauling. Engineered to accommodate a 1.5-inch lift, this set provides the necessary travel and valving to maintain stability and comfort across diverse driving conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance under heavy use.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade resistance.
• All-Weather Fluid: Specialized synthetic oil provides consistent viscosity from -40 to 248 degrees Fahrenheit to ensure smooth operation in extreme climates.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body. You can manually turn the dial to increase or decrease damping resistance without tools.

Do these shocks provide the 1.5-inch lift?
No, these shocks are specifically valved and length-matched for a vehicle that already has a 1.5-inch lift installed. They do not create lift themselves.

Are these shocks suitable for towing?
Yes, the higher settings (7-9) on the adjustment dial are specifically engineered to provide the extra damping required to control trailer sway and heavy bed loads.
