Rancho RS9000XL 5-6″ Rear Lift Shocks for 2001-2007 GMC Sierra 1500HD

Part Number: RS999056

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications through its globally recognized 9-position manual tuning system. By allowing drivers to adjust damping levels on the fly, these shocks solve the common conflict between highway comfort and the firm control required for towing or off-road excursions. Specifically configured for vehicles with 5-6 inches of rear lift, these shocks deliver a custom-tuned ride quality that adapts to your specific load requirements and terrain.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure precise control for everything from daily commuting to heavy hauling.
• Large Shock Body: A massive 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operation and consistent performance during long-travel cycles.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Heavy-Duty Piston: A 18mm nitro-carbonized rod provides extreme structural rigidity to ensure long-term durability under harsh off-road conditions.
