Rancho RS9000XL 5-6″ Lift Shocks for 1999-2006 Chevy Silverado 1500 4WD Torsion

Part Number: RS999057

Summary: The Rancho RS9000XL series provides unparalleled versatility for your Chevy or GMC truck with its industry-leading 9-position manual tuning system. By utilizing a global compression adjustment knob, these shocks allow you to instantly switch between a soft street ride and a firm setting for heavy towing or aggressive off-road use. Engineered to accommodate 5-6 inches of lift, this set ensures your leveled or lifted vehicle maintains optimal suspension travel and control regardless of the terrain.

Features

• 9-Position Tuning: A manual adjustment knob provides a 400% change in damping control to ensure the vehicle is perfectly dialed in for towing, hauling, or street cruising.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping performance in demanding environments.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and smooth oil flow to ensure long-term durability on and off the road.
