Rancho RS9000XL 4″ Rear Lift Shocks for 1992-1999 GMC Suburban 1500 4WD

Part Number: RS999227

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their vehicle’s ride profile. Featuring a 9-position manual tuning knob, these shocks allow you to instantly switch between a soft street ride and a firm setting for heavy towing or off-road stability. Specifically configured for GMC Suburban 1500 models with a 4-inch rear lift, these shocks solve the problem of “one-size-fits-all” valving by putting the damping control directly in your hands.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect ride for any load or terrain.
• Large Diameter Body: The 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operation and consistent performance under heavy use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure the tires maintain constant contact with the road surface.
• Protective Boot: A durable poly-vinyl accordion boot protects the shock rod from debris to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
The shocks feature a manual 9-position knob located at the base of the shock body. No tools are required; simply turn the dial to your desired firmness level.

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically designed to accommodate the extended travel requirements of a vehicle already equipped with a 4-inch rear lift kit.

What is the benefit of the nitrogen gas charging?
The nitrogen gas minimizes the aeration of the hydraulic fluid, which prevents “shock fade” and ensures consistent damping even during rapid cycling on rough roads.
