Rancho RS9000XL 3″ Rear Lift Shocks for 1983-1993 GMC S-15 4WD

Part Number: RS999124

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their suspension damping. Featuring a 9-position manual tuning knob, these shocks allow you to instantly switch between a soft street ride and firm damping for heavy towing or off-road excursions. Specifically configured for 3-inch rear lift applications, these shocks solve the problem of “one size fits all” valving by putting the final calibration in the driver’s hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping force to ensure custom-tailored ride quality for any terrain or load.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance during high-intensity use.
• Nitrogen Gas Charged: High-pressure gas displacement provides reduced aeration and foaming to ensure immediate response and fade resistance.
• Heavy-Duty Rod: A 18mm nitro-carburized piston rod provides superior structural rigidity to ensure long-term durability in harsh environments.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
These shocks feature an external 9-position knob located at the base of the shock body. You can manually turn the dial to increase or decrease damping resistance without tools.

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to accommodate a vehicle already equipped with a 3-inch rear lift kit.

What setting should I use for daily driving?
Most drivers find that settings 1 through 3 provide the smoothest street performance, while settings 7 through 9 are ideal for heavy towing or high-speed off-road stability.
