Rancho RS9000XL 2.5-4″ Rear Lift Shocks for 1992-1998 Chevy Suburban & Yukon 2500 4WD

Part Number: RS999227

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty SUVs through its signature 9-position manual tuning system. By utilizing a global compression adjustment knob, these shocks allow owners to instantly transition from a soft street ride to a firm high-performance setting for towing or off-road use. Engineered for vehicles with 2.5 to 4 inches of rear lift, these shocks solve the common issue of “one-size-fits-all” valving by putting damping control directly in the driver’s hands.

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 2.75-inch diameter tube provides increased fluid capacity to ensure lower operating temperatures during heavy-duty towing.
• Nitrogen Gas Charged: High-pressure gas optimization provides consistent valving response to ensure reduced aeration and foaming.
• Polyurethane Bushings: Durable polyurethane material provides enhanced road feel and longevity to ensure quiet, reliable operation over the life of the vehicle.

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. You can turn it by hand to increase or decrease damping resistance.

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically valved and lengthened to be compatible with vehicles already equipped with a 2.5 to 4-inch rear lift kit.

Are these shocks suitable for towing?
Yes, the RS9000XL is ideal for towing. By turning the adjustment knob to a higher setting (7-9), you can significantly reduce sway and “porpoising” when hauling heavy loads.
