Rancho RS9000XL 6″ Rear Lift Shocks for 2014-2018 GMC Sierra 1500

Part Number: RS994297

Summary: The Rancho RS9000XL series is the industry benchmark for user-adjustable ride control, designed to provide ultimate versatility for your lifted GMC Sierra 1500. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy towing or aggressive off-road use. Engineered for vehicles with a 6-inch rear lift, these large-body shocks provide the increased fluid capacity necessary to maintain consistent damping performance under high-stress conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for any terrain or load requirement.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during long-distance hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road imperfections to ensure consistent tire-to-ground contact.
• Protective Boot: An included heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
