Rancho RS9000XL 0″ Rear Lift Shocks for 1967-1972 GMC C3500 2WD

Part Number: RS999113

Summary: The Rancho RS9000XL series delivers industry-leading versatility for classic GMC heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly adjust damping levels to compensate for varying payloads or towing requirements. This Tier 2 adjustable technology transforms the ride quality of the GMC C3500, offering a soft setting for empty-bed street cruising and a firm setting for maximum control under load.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride for towing, hauling, or daily driving.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure consistent performance and reduced fade during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road imperfections to ensure a smooth, controlled ride.
• Protective Boot: A heavy-duty liquid metallic finish and included bellows boot provide a physical barrier against debris to ensure long-term seal durability.

Why Choose This Product?

• Performance Benefit: Drivers gain the ability to eliminate “rear-end sag” feel and wallowing by simply clicking the dial to a firmer setting when the truck is loaded.
