Rancho RS90000XL 4″ Front Lift Shocks for 2001-2010 Chevy Silverado 2500HD

Part Number: RS999289

Summary: The Rancho RS90000XL series provides industry-leading adjustability for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly transition from a soft street ride to a firm setting optimized for towing or aggressive off-road use. Engineered for vehicles equipped with a 4-inch lift, they provide the necessary travel and damping control to manage the increased unsprung weight of larger wheel and tire packages.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can fine-tune ride quality for varying loads or terrains.
• Large Diameter Body: The 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operation and consistent performance during high-demand cycles.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Protective Boot: A heavy-duty liquid metallic finish and included poly-vinyl boot provide protection for the piston rod to ensure long-term durability against road debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS90000XL features a 9-position knob located at the base of the shock; simply turn the dial to your preferred setting (1 for softest, 9 for firmest).

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to function on vehicles already equipped with a 4-inch lift kit.

Can these be used with non-Rancho lift kits?
While optimized for Rancho Suspension systems, they may work with other 4-inch lifts; however, you must verify that the collapsed and extended lengths match your specific suspension travel requirements.
