Rancho RS9000XL Series Adjustable Front Shock for 2006-2009 Hummer H3 and H3T - RS999309

Fits 2006-2009 Hummer H3 and H3T models, including Base, Adventure, Alpha, Luxury, X, and Championship Series. This Rancho RS9000XL front shock absorber (MPN: RS999309) provides an industry-leading nine levels of manual damping adjustment, allowing you to fine-tune your suspension for highway comfort, heavy towing, or technical off-road use.

Engineered for hardworking vehicles, the RS9000XL features a large 2.75-inch tri-tube body filled with all-weather fluid to maintain cooler operating temperatures under high-stress conditions. The nitrogen gas charge, pressurized to 120 PSI, significantly reduces oil foaming and damping fade. Built to withstand extreme environments, it is rated for internal temperatures ranging from -40°F to 248°F.

• Adjustable Control: 9-position manual knob for customized compression and rebound damping.
• Heavy-Duty Construction: 18mm nitro-carburized piston rod resists scuffs and corrosion; 1.25-in. sintered iron piston for structural integrity.
• Durability: Double-welded loops at high-stress points and a premium liquid metallic finish with a polyvinyl protective boot.
• Smooth Operation: Graphite-filled Fluon-banded piston and polyurethane bushings for improved responsiveness.

Includes a self-lubricating, low-friction seal to retain gas and oil, ensuring quicker rebound and smoother compression throughout the life of the shock.
