Rancho RS9000XL 1-2.5″ Front Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS999152

Summary: The Rancho RS9000XL series provides industry-leading adjustability for GMC K1500 owners seeking a customizable ride profile. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition between a soft street feel and a firm setting optimized for towing or off-road stability. Engineered specifically for vehicles with 1-2.5 inches of front lift, these shocks solve the compromise between daily comfort and heavy-duty performance.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the vehicle is perfectly tuned for any terrain or load requirement.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides consistent valving response to ensure reduced aeration and foaming.
• Protective Boot: A heavy-duty liquid metallic finish and included poly-vinyl boot provide a secondary layer of protection to ensure the piston rod remains free from debris and corrosion.

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, with 1 being the softest and 9 being the firmest.

Will these shocks lift my GMC K1500?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 1 to 2.5 inches of front lift height installed.

What is the benefit of the larger 2.75-inch body?
The increased diameter allows for a larger fluid reservoir, which helps dissipate heat faster than standard shocks, preventing performance fade during spirited driving or heavy work.
