Rancho RS9000XL 4″ Front Lift Shocks for 1988-1999 GMC K1500 4WD
Part Number: RS999244
Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC K1500 and Yukon, featuring 9-position manual tuning technology. This adjustable damping system allows owners to transition from a soft street ride to a firm setting for heavy towing or off-road stability at the turn of a dial. Engineered for vehicles equipped with a 4-inch lift, these shocks provide the necessary travel and control to maintain ride quality on increased ride heights.
Features
- MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping control to ensure the vehicle is perfectly calibrated for daily driving, towing, or off-road use.
- Large Diameter Body: The 2.75-inch tri-tube body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
- Nitrogen Gas Charging: Pressurized nitrogen gas minimizes air-to-oil mixture (aeration) to provide consistent damping response and fade resistance.
- Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions
How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body; simply turn the dial to your desired setting without the need for tools.
Do these shocks provide 4 inches of lift?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with a vehicle already equipped with a 4-inch suspension lift.
What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat more effectively, preventing performance fade during aggressive off-road use or heavy hauling.
