Rancho RS9000XL 0-2″ Front Lift Shocks for 1977-1986 GMC K3500 4WD

Part Number: RS999151

Summary: The Rancho RS9000XL series is the industry leader in adjustable damping, providing a custom-tailored ride for your GMC K3500. Featuring a 9-position manual tuning knob, these shocks allow you to instantly switch between a soft street ride and firm control for towing or heavy off-road use. Engineered for vehicles with 0-2 inches of front lift, they solve the compromise between daily comfort and heavy-duty performance by putting damping control directly in the driver’s hands.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect ride quality 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 and reduced fade during heavy use.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a reduction in air-to-oil mixture (foaming) to ensure consistent damping performance.
• Heavy-Duty Piston: A 18mm nitro-carburized rod provides structural rigidity and scuff resistance to ensure long-term seal integrity in harsh environments.

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. Simply turn the dial to your desired setting; 1 is the softest and 9 is the firmest.

Will these shocks lift my GMC K3500?
No, these shocks do not create lift. They are specifically valved and length-configured to work with vehicles already equipped with 0 to 2 inches of front lift.

Do these come with the red boots shown in pictures?
Yes, these shocks include Rancho’s signature red protective boots to shield the piston rod from debris and corrosion.
