Rancho RS90000XL 5-6″ Rear Lift Shocks for 2001-2010 Chevy Silverado 2500HD

Part Number: RS999056

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for towing or aggressive off-road use. Engineered for vehicles with 5-6 inches of rear lift, these shocks solve the compromise between daily comfort and heavy-load stability.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping force to ensure the perfect ride quality for any terrain or load requirement.
• Large Diameter Body: A 2.75-inch heavy-duty reserve tube provides increased oil capacity to ensure cooler operating temperatures during long-distance hauling.
• Nitrogen Gas Pressurized: High-pressure gas charges provide immediate response and prevent oil foaming to ensure consistent performance under high-stress cycles.
• Protective Boot: A durable polyvinyl accordion boot protects the 18mm nitro-carburized piston rod from debris to ensure long-term seal integrity.

Why Choose This Product?

• Engineering Advantage: Rancho’s MyRide technology allows for a 400% change in damping force across the 9-position spectrum, offering more control than any fixed-valve shock.
• Performance Benefit: The ability to firm up the rear suspension eliminates “squat” and “sway” while towing, while the softer settings prevent the harsh “empty bed” bounce common in HD trucks.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual knob located at the base of the shock body. Simply turn the dial to setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks create 6 inches of lift?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to function on a vehicle that already has a 5-6 inch lift kit installed.

Are these shocks nitrogen charged?
Yes, these shocks are nitrogen gas pressurized to optimize piston response and minimize aeration during rapid suspension cycling.
