Rancho RS9000XL 2.5-4″ Lift Shocks for 1969-1991 GMC Suburban 1500 4WD

Part Number: RS999001

Summary: The Rancho RS9000XL series delivers industry-leading versatility for GMC Suburban owners who demand manual control over their ride quality. Featuring a globally recognized 9-position adjustment knob, these shocks allow you to instantly tune your suspension damping to accommodate heavy towing, off-road trekking, or smooth highway cruising. Engineered for vehicles with 2.5 to 4 inches of lift, this set provides the necessary travel and valving to maintain stability and comfort in any driving environment.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the driver can switch between a soft street ride and firm off-road performance.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping response under high-stress cycles.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against trail debris.
