Rancho RS9000XL 5-6″ Front Lift Shocks for 1999-2004 GMC Sierra 2500 4WD

Part Number: RS999055

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications, featuring a 9-position manual tuning knob that allows drivers to adjust damping levels on the fly. Engineered to accommodate GMC Sierra 2500 and Hummer H2 models with 5 to 6 inches of front lift, these shocks solve the compromise between street comfort and off-road stability. Whether you are towing a heavy trailer or navigating rugged terrain, the RS9000XL provides the ability to firm up the ride for control or soften it for daily commuting.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure custom-tailored ride control for towing, hauling, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance under high-load conditions.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Protective Boot: A heavy-duty liquid metallic finish and included shock boot provide protection against road debris and corrosion to ensure long-term durability.

Frequently Asked Questions

Do I need tools to adjust the stiffness of these shocks?
No, the RS9000XL features an external 9-position knob that can be turned by hand, allowing for quick adjustments without specialized tools.

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically engineered with the correct extended and compressed lengths to fit vehicles already equipped with a 5-6″ lift kit.

What is the benefit of the larger shock body?
The larger 2.75-inch body holds more oil, which helps dissipate heat faster than standard shocks, preventing performance fade during heavy-duty use.
