Rancho RS9000XL 4″ Lift Shocks for 2006-2009 Hummer H3

Part Number: RS999309 (Full Set)

Summary: The Rancho RS9000XL series provides industry-leading versatility for the Hummer H3 through its signature 9-position manual tuning system. By utilizing a global compression adjustment knob, these shocks allow owners to instantly transition from a soft street ride to a firm, controlled setting for heavy towing or off-road excursions. Engineered specifically for H3 models equipped with a 4-inch Rancho suspension system, these large-body shocks deliver consistent damping and heat dissipation under demanding loads.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for any terrain or load requirement.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during sustained off-road use.
• Nitrogen Gas Charged: High-pressure gas displacement provides immediate response and prevents oil foaming to ensure consistent performance.
• Protective Boot: A heavy-duty liquid metallic finish and included dust boot provide maximum protection for the piston rod to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features a manual knob located at the base of the shock body. Simply turn the dial to your desired setting (1 for softest, 9 for firmest).

Will these shocks lift my Hummer H3?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with a Hummer H3 that already has a 4-inch lift kit installed.

What setting is best for towing?
For towing or heavy hauling, it is recommended to use a higher setting (typically 7-9) to increase stability and reduce vehicle sway.
