Rancho RS9000XL 2.5-4″ Front Lift Shocks for 1987-1991 GMC V3500 4WD

Part Number: RS999001

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC V3500, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable technology allows drivers to instantly transition from a soft street ride to a firm, controlled setting for heavy towing or off-road excursions. Engineered to accommodate 2.5 to 4 inches of front lift, these shocks provide a custom-tuned damping solution that eliminates the compromises of traditional fixed-rate suspension.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure precise ride control across various terrains and load requirements.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a consistent response and minimizes aeration to ensure fade-free performance during aggressive cycling.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures under high-stress conditions.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road 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 preferred setting—lower numbers for a softer ride and higher numbers for increased firmness.

Do these shocks create the lift for my GMC V3500?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with vehicles already equipped with a 2.5 to 4-inch lift kit.

What is the benefit of the larger shock body?
The 2.75-inch diameter body holds more oil than standard shocks, which helps dissipate heat more efficiently, preventing performance fade during long trips or off-road use.
