Part Number: RS999289

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their suspension damping. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered to accommodate a 4-inch lift, these shocks solve the problem of “one size fits all” valving by putting the final ride quality in the driver’s hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride for any terrain or load requirement.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response and minimizes aeration to ensure fade-free performance.
• Polyurethane Bushings: High-density polyurethane material provides improved durability and reduced deflection to ensure precise steering response.
