Rancho RS9000XL 4″ Front Lift Shocks for 1988-2000 GMC C2500 2WD

Part Number: RS999128

Summary: The Rancho RS9000XL series provides industry-leading versatility for owners of the GMC C2500 2WD. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from a soft street ride to a firm setting for heavy towing or hauling. Engineered to accommodate a 4-inch front lift, they deliver customized ride control that adapts to your specific driving environment.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect balance between comfort and control.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a consistent response and minimizes aeration to ensure fade-free performance during spirited driving.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Protective Boot: A durable poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity.
