Rancho RS90000XL 4″ Rear Lift Shocks for 2001-2007 Chevy Silverado 1500HD Torsion Bar

Part Number: RS994297

Summary: The Rancho RS90000XL series provides ultimate control for drivers who demand versatility from their heavy-duty suspension. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your ride stiffness to match shifting loads or terrain changes. Whether you are daily driving, towing a heavy trailer, or heading off-road, this adjustable damping system solves the “one size fits all” compromise of standard shocks.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure custom-tailored ride control for any load or road condition.
• Large Shock Body: A massive 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a consistent response and minimizes aeration to ensure fade-free performance in demanding environments.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the oil seal and piston rod to ensure long-term durability against road debris.

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 desired setting; 1 is the softest and 9 is the firmest.

Do these shocks provide 4 inches of lift?
No, these shocks do not create lift. They are specifically valved and length-configured to work with vehicles that have already been equipped with a 4-inch suspension lift kit.

Can I use these on a stock height vehicle?
No, these shocks are designed with an extended length of 30.47 inches to accommodate lift kits. Installing them on a stock height vehicle may result in the shock bottoming out and causing internal damage.
