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

Part Number: RS999055

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications, featuring a globally recognized 9-position manual adjustment knob. This system allows owners of lifted GMC Sierra 1500HD and Hummer H2 vehicles to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Engineered for vehicles with 5 to 6 inches of lift, these shocks provide the necessary stroke and damping control to manage increased unsprung weight and higher centers of gravity.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the vehicle is perfectly tuned for specific payloads or terrain.
• Large Diameter Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during long-distance hauling or trail runs.
• Nitrogen Gas Pressurization: A high-pressure gas charge provides a consistent response and minimizes aeration to ensure fade-free performance in demanding environments.
• Protective Boot: A durable liquid metallic finish and included red dust boot provide maximum rod protection 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 located at the base of the shock body. Simply turn the dial to your desired setting, with 1 being the softest and 9 being the firmest.

Will these shocks provide my vehicle with a 6-inch lift?
No, these shocks do not create lift. They are specifically long-travel dampers configured to work with vehicles that already have a 5-6″ suspension lift kit installed.

Are these shocks suitable for towing heavy trailers?
Yes, the adjustable nature of the RS9000XL makes them ideal for towing; increasing the damping to a higher setting helps control trailer sway and rear-end porpoising.
