Rancho RS9000XL 5-6″ Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS999059 / RS999060

Summary: The Rancho RS9000XL series provides industry-leading adjustability for GMC K1500 owners seeking a tailored ride quality on lifted applications. 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 to accommodate 5-6 inches of suspension lift, this set ensures your Yukon maintains optimal damping control and stability regardless of the terrain or cargo load.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom-tailored ride control for various road conditions.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during rapid cycling.
• Large Diameter Shock Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during demanding use.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a shield for the piston rod to ensure long-term seal integrity against debris.
