Part Number: RS999118

Summary: The Rancho RS9000XL series provides unparalleled ride control for the 1963-1972 GMC C2500. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your suspension damping to match specific towing, hauling, or street driving requirements. Engineered to accommodate a 1.5-inch rear lift, they provide the necessary travel and damping force to maintain stability and comfort in classic heavy-duty applications.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the driver can transition from a soft street ride to firm control for heavy hauling.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent damping performance during spirited driving or heavy-duty use.
• Large Diameter Body: A heavy-duty shock body provides increased fluid capacity to ensure lower operating temperatures and reduced fade during long-distance towing.
• Protective Boot: A durable red polyvinyl accordion boot provides a shield for the shock rod to ensure the seal remains free from road debris and contaminants.
