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

Part Number: RS999227

Summary: The Rancho RS9000XL series provides industry-leading versatility for the GMC K2500, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows drivers to instantly tune damping levels to compensate for varying payloads or off-road conditions. Engineered for vehicles with 2.5 to 4 inches of rear lift, these shocks solve the compromise between street comfort and heavy-duty towing stability.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride quality for towing, hauling, or daily driving.
• Large Diameter Body: A massive 2.75-inch shock body provides increased fluid capacity to ensure consistent performance and reduced fade under high-heat conditions.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road irregularities to ensure tire-to-ground contact is maintained.
• Protective Boot: A heavy-duty liquid metallic finish and included boot provide a durable barrier against debris to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body, allowing for manual tuning without tools or removal.

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

What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat faster and prevents the “fading” feeling during prolonged use or heavy towing.
