Part Number: RS999190

Summary: The Rancho RS9000XL series provides industry-leading adjustability for owners of the GMC K1500 and Yukon. 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 off-road excursions. Engineered to accommodate rear lift heights of 1 to 2.5 inches, they offer a customizable damping solution that eliminates the compromise between comfort and control.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping force 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 and consistent performance during heavy use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure the tires maintain maximum contact with the road surface.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and smooth fluid flow to ensure long-term durability in demanding environments.
