Rancho RS9000XL 4″ Rear Lift Shocks for 1988-2000 Chevy K3500 4WD

Part Number: RS999227

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying loads or terrain. This Tier 2 adjustable system solves the compromise between stiff towing stability and unloaded street comfort, specifically configured for vehicles equipped with a 4-inch rear lift.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for towing, hauling, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a faster response rate to ensure consistent tire-to-road contact on uneven surfaces.
• Heavy-Duty Piston: A 18mm nitro-carburized rod provides exceptional structural rigidity to ensure long-term durability under extreme stress.

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 firmer damping.

Do these shocks create a 4-inch lift?
No, these shocks do not create lift. They are specifically valved and sized to accommodate vehicles that already have a 4-inch rear lift kit installed.

Will these fit a 2WD Chevy K3500?
These specific units are engineered for the 4WD (K-Series) chassis as listed in the fitment data and may not be compatible with 2WD (C-Series) mounting configurations.
