Rancho RS9000XL 4″ Lift Shocks for 2007-2014 GMC Yukon XL 1500

Part Number: RS999786 / RS999274

Summary: The Rancho RS9000XL series provides the ultimate in ride control for the GMC Yukon XL 1500, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows owners to instantly tune damping levels to compensate for varying payloads or terrain transitions. Engineered to accommodate a 4-inch lift, these shocks solve the common issue of compromised ride quality after suspension modification by offering a customizable bridge between street comfort and off-road firmness.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping to ensure the driver can transition from soft street cruising to firm towing support.
• 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 Pressurization: High-pressure gas charging provides a consistent response by minimizing oil foaming and aeration to ensure fade-free performance.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability and reduced deflection to ensure precise handling and longevity.
