Summary: The Rancho RS9000XL series delivers industry-leading flexibility for GMC K3500 owners who demand performance across varying terrains and load conditions. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy towing or off-road use. Engineered for vehicles with 4-inch lifts, these shocks provide the necessary travel and damping control to maintain stability on and off the pavement.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for street, towing, or off-road applications.
• 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 in rugged conditions.
• Polyurethane Bushings: Heavy-duty polyurethane material provides enhanced durability and responsiveness to ensure long-lasting pivot point integrity.
