Rancho RS9000XL 1.5″ Front Lift Shocks for 1967-1986 GMC C1500 / Jeep Wagoneer

Part Number: RS999120

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for vintage GMC and Jeep applications. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow owners to instantly tune damping levels to suit specific driving conditions, from soft street cruising to firm heavy-duty towing. Engineered to accommodate a 1.5-inch front lift, they provide the necessary travel and damping force to maintain stability and comfort in classic 2WD and 4WD configurations.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can transition between soft comfort and firm performance.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping during spirited or off-road driving.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure lower operating temperatures and reduced fade under load.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability and responsiveness to ensure a long service life compared to standard rubber.

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 increase or decrease damping resistance.

Do these shocks provide the 1.5 inches of lift?
No, these shocks are specifically valved and length-indexed to be compatible with vehicles that have already been equipped with 1.5 inches of front lift components.

What is the benefit of the larger shock body?
The 2.75-inch body holds more hydraulic fluid, which helps dissipate heat faster, preventing the shock from becoming “soft” or “faded” during heavy use.
