Rancho RS9000XL 4″ Lift Shocks for 2001-2007 GMC Sierra 1500HD

Part Number: RS999296 / RS994297

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty GMC applications through its globally recognized 9-position manual tuning system. By allowing drivers to adjust damping levels across nine distinct settings, these shocks solve the common conflict between highway comfort and heavy-load stability. Engineered specifically for vehicles equipped with a 4-inch lift, these shocks ensure the suspension geometry remains optimized while delivering a custom-tailored ride quality for any terrain or towing requirement.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between street comfort and off-road firmness.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy towing or hauling.
• Nitrogen Gas Pressurized: High-pressure gas charge provides a reduction in aeration and foaming to ensure consistent damping performance under high-cycle use.
• Polyurethane Bushings: High-performance shock bushings provide enhanced durability and reduced deflection to ensure precise handling and steering response.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body; simply turn the dial to your preferred setting (1 for softest, 9 for firmest).

Do these shocks provide the 4-inch lift?
No, these shocks do not create lift. They are specifically valved and length-indexed to work with vehicles that already have a 4-inch suspension lift installed.

Will these fit a stock height GMC Sierra 1500HD?
No, these are specifically designed for vehicles with 4 inches of lift. Installing them on a stock height vehicle may result in the shock bottoming out and sustaining internal damage.
