Rancho RS9000XL 4″ Lift Shocks for 2003-2009 Hummer H2

Part Number: RS999289 / RS994297

Summary: The Rancho RS9000XL series delivers a premium adjustable damping experience for the Hummer H2 equipped with a 4-inch lift. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly transition from a soft street ride to a firm setting for heavy towing or off-road stability. Engineered for high-performance use, the large-bore design provides the fluid capacity necessary to maintain consistent damping under the heavy unsprung mass of the H2 platform.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping control to ensure the vehicle is perfectly tuned for street, towing, or off-road applications.
• Large Diameter Body: The 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures and reduced fade during aggressive maneuvers.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a rapid response rate and minimizes aeration to ensure consistent valving performance.
• Polyurethane Bushings: High-durometer polyurethane material provides enhanced durability and reduced deflection to ensure precise handling and road feedback.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Each shock features a red 9-position knob located near the base. Simply turn the dial to setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks lift my Hummer H2 by 4 inches?
No, these shocks do not create lift. They are specifically valved and sized to accommodate a Hummer H2 that already has a 4-inch suspension lift installed.

Are the protective boots included?
Yes, this set includes Rancho’s signature red protective boots to shield the piston rod from debris and off-road contaminants.
