Rancho RS9000XL 2.5-4″ Rear Lift Shocks for 1987 GMC V2500 4WD

Part Number: RS999112

Summary: The Rancho RS9000XL series provides industry-leading versatility for owners who demand total control over their vehicle’s damping profile. 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 excursions. Engineered to accommodate 2.5 to 4 inches of rear lift, these shocks solve the problem of “one size fits all” valving by putting the tuning power directly in the driver’s hands.

Features

• MyRide 9-Position Tuning: A manually adjustable damping knob provides nine distinct levels of compression and rebound resistance to ensure the perfect ride quality for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance during heavy-duty use.
• Nitrogen Gas Pressurization: High-pressure gas charge provides a literal barrier against oil foaming and aeration to ensure fade-free damping response.
• Protective Boot Included: A heavy-duty red polyvinyl accordion boot provides a physical shield for the piston rod to ensure long-term seal integrity against debris.

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; position 1 is the softest and position 9 is the firmest.

Do these shocks provide lift to my GMC V2500?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to function on vehicles already equipped with a 2.5 to 4-inch rear lift kit.

Will these shocks help with towing stability?
Yes. By increasing the setting on the adjustment knob, you increase the damping force, which helps control trailer sway and rear-end “squat” oscillations during towing.
