Rancho RS9000XL 2.5-4″ Front Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS999001

Summary: The Rancho RS9000XL series provides industry-leading adjustability for GMC K2500 owners seeking a customizable ride profile. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street feel to a firm setting for heavy towing or aggressive off-road use. Engineered for vehicles with 2.5 to 4 inches of front lift, this nitrogen-gas charged solution eliminates the “one size fits all” compromise of standard dampers.

Features

• 9-Position Tuning Knob: Manual adjustment technology provides 400% change in damping control to ensure the perfect ride for any terrain or load.
• Large 2.75-in. Body: Increased fluid capacity provides cooler operation and reduced fade to ensure consistent performance during heavy-duty cycles.
• Nitrogen Gas Pressurization: High-pressure gas charge provides a reduction in aeration and foaming to ensure rapid valve response and precision handling.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual dial at the base of the shock; simply turn the knob to setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks lift my GMC K2500?
No, these shocks are designed to work with a vehicle already equipped with a 2.5 to 4-inch lift kit; they do not create lift height themselves.

Can I use these on a stock height truck?
These shocks are specifically valved and sized for vehicles with 2.5-4 inches of lift; using them on a stock height truck may result in the shock bottoming out and sustaining damage.
