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

Part Number: RS999001

Summary: The Rancho RS9000XL series delivers industry-leading versatility for owners who demand total control over their ride quality. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. These nitrogen-gas pressurized units are specifically configured for GMC K2500 models with 2.5 to 4 inches of front lift, providing a massive shock body for increased oil capacity and cooler operation under load.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect balance between comfort and control for any terrain.
• Large 2.75-inch Body: An oversized shock housing provides increased fluid capacity to reduce internal temperatures and ensure fade-free performance during heavy-duty use.
• Nitrogen Gas Pressurization: High-pressure gas charging minimizes oil foaming and aeration to ensure consistent damping response in rapid-cycling environments.
• Liquid Metallic Finish: A premium zinc-plated coating provides superior corrosion resistance to ensure long-term durability in harsh underbody conditions.

Why Choose This Product?

• Performance Benefit: Drivers gain the ability to firm up the front end for highway stability and soften it for improved articulation and compliance when off-road.

Frequently Asked Questions

How do I adjust the stiffness 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—1 for the softest ride and 9 for maximum firmness.

Will these shocks lift my GMC K2500?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles already equipped with a 2.5 to 4-inch suspension lift kit.

Are the dust boots included?
Yes, these shocks come standard with Rancho’s signature red protective boots to shield the piston rod from debris and contaminants.
