Rancho RS9000XL 0″ Rear Lift Shocks for 1967-1972 GMC C2500 2WD

Part Number: RS999113

Summary: The Rancho RS9000XL series delivers industry-leading versatility for classic GMC trucks, featuring a globally recognized 9-position manual adjustment knob. This system allows owners to instantly transition between a soft street ride and a firm setting for hauling or towing, addressing the varied demands placed on C2500 workhorses. Engineered for vehicles with rear coil springs, these shocks provide a custom-tuned feel without the need for complex suspension overhauls.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for any load or terrain.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during heavy-duty cycling.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during prolonged use.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and smooth fluid bypass to ensure precise valving response.
