Rancho RS9000XL 4″ Rear Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS999269

Summary: The Rancho RS9000XL series provides industry-leading versatility for drivers who demand total control over their vehicle’s damping profile. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Engineered for vehicles with a 4-inch rear lift, these shocks solve the problem of “one size fits all” valving by putting the tuning power directly in the driver’s hands.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect ride quality 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 during heavy-duty use.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Heavy-Duty Nitro-Carburized Rod: A 18mm diameter piston rod provides superior structural rigidity and corrosion resistance to ensure long-term durability in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body. Simply turn the dial to your desired setting; 1 is the softest and 9 is the firmest.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and valved to work with vehicles that have already been equipped with a 4-inch rear lift kit.

What is the benefit of the larger 2.75-inch body?
The larger body holds more oil, which helps dissipate heat faster. This prevents the shock from “fading” or losing its damping effectiveness during long trips or rough off-road sections.
