Rancho RS9000XL 5-6″ Lift Shocks for 2000-2009 Hummer H2

Part Number: RS999055 / RS999056

Summary: The Rancho RS9000XL series provides the ultimate level of manual ride control for the Hummer H2 platform. Featuring a signature 9-position adjustment knob, these shocks allow owners to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Engineered to accommodate 5 to 6 inches of suspension lift, this complete set delivers a massive shock body for increased oil capacity and consistent damping under high-stress conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for any terrain or load requirement.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during long-distance hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road imperfections to ensure consistent tire-to-ground contact.
• Protective Boot: A durable red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.

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 lift my Hummer H2?
No, these shocks do not create lift. They are specifically valved and length-indexed to function correctly on a Hummer H2 that already has a 5″ to 6″ lift kit installed.

What is the benefit of the large 2.75-inch body?
The oversized body allows for more oil capacity. More oil means the shock can dissipate heat more effectively, preventing “shock fade” during heavy towing or off-road use.
