Rancho RS9000XL 5-6″ Front Lift Shocks for 2001-2007 GMC Sierra 1500HD

Part Number: RS999055

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications and lifted trucks. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying payloads or terrain. Whether you are daily driving your GMC Sierra 1500HD or towing a heavy trailer with your Hummer H2, this adjustable solution eliminates the compromise between street comfort and off-road control.

Features

• MyRide Tuning System: A 9-position manual adjustment knob provides custom damping control to ensure optimal ride quality across nine different performance levels.
• Large Diameter Body: A 2.75-inch heavy-duty reserve tube provides increased fluid capacity to ensure cooler operation during high-stress hauling or off-road use.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a barrier between the oil and gas to ensure consistent performance by preventing aeration and foaming.
• Protective Boot: A durable red polyvinyl accordion boot provides a physical shield for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob at the base of the shock body. Simply turn the dial to your desired setting; no tools or air lines are required.

Do these shocks provide the 5-6 inches of lift?
No, these shocks do not create lift. They are specifically valved and extended in length to function correctly on vehicles already equipped with a 5-6″ suspension lift kit.

What is the benefit of the larger 2.75-inch body?
The increased oil capacity allows the shock to dissipate heat more effectively, which prevents “shock fade” during aggressive driving or heavy-duty towing.
