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 towing or off-road stability. Engineered for vehicles with 1.5 inches of rear lift, they provide the ideal solution for balancing daily commute comfort with heavy-duty performance requirements.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride quality for any terrain or load.
• Nitrogen Gas Charging: Pressurized gas provides a reduction in aeration and foaming to ensure consistent damping performance during spirited driving.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and reduced fade under heavy stress.
• Polyurethane Bushings: High-density polyurethane material provides improved durability and responsiveness to ensure a long-lasting service life compared to standard rubber.
