Part Number: RS999274

Summary: The Rancho RS9000XL series provides unparalleled versatility for your GMC Sierra 2500HD by utilizing a 9-position manual tuning knob. This Tier 2 adjustable technology allows drivers to instantly shift between a soft street ride and a firm setting for heavy towing or hauling. Engineered to handle the demands of a heavy-duty truck, these shocks provide a custom-tuned feel for any terrain or load capacity.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the perfect ride for towing, hauling, or daily commuting.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure consistent performance and reduced fade during heavy-duty use.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier against oil aeration to ensure immediate response and consistent damping.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability and responsiveness to ensure a long-lasting connection to the chassis.

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 that can be turned by hand to increase or decrease firmness.

Will these shocks lift my vehicle?
No, these shocks are configured for a 0-inch lift height and are designed to replace factory-length shocks without changing the vehicle’s ride height.

What is the benefit of the large 2.75-inch body?
The larger body houses more oil, which helps dissipate heat more effectively, preventing the shock from becoming “soft” or “faded” during heavy work or long trips.
