Rancho RS9000XL 4″ Front Lift Shocks for 2004-2008 Infiniti QX56

Part Number: RS999773

Summary: The Rancho RS9000XL series provides industry-leading versatility for owners who demand total control over their vehicle’s ride quality. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street feel to a firm setting optimized for towing or aggressive off-road use. Engineered to work specifically with the Rancho RS6594B system, these shocks provide the necessary damping profile for vehicles equipped with a 4-inch lift.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can customize ride firmness for any terrain or load.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent damping performance.
• Heavy-Duty Piston: A 18mm nitro-carburized piston rod provides structural rigidity and scuff resistance to ensure long-term seal integrity.
