Part Number: RS994297

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty applications. Featuring a globally recognized 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying payloads or terrain. Whether you are towing a heavy trailer or driving unladen on the highway, this Tier 2 adjustable system ensures optimal ride control and comfort for your lifted vehicle.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during demanding off-road use.
• Nitrogen Gas Pressurized: High-pressure gas charge minimizes air-to-oil mixture (foaming) to provide consistent damping performance and rapid response.
• Nitro-Carburized Piston Rod: A 18mm heavy-duty rod construction provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a 9-position knob located at the base of the shock body. Simply turn the dial to your desired setting, with 1 being the softest and 9 being the firmest.

Do these shocks provide 4 inches of lift?
No, these shocks do not create lift. They are specifically engineered with the correct extended and compressed lengths to accommodate vehicles already equipped with a 4-inch rear lift kit.

Will these work with my stock height truck?
No, these are extended-length shocks designed specifically for vehicles with 4 inches of rear lift. Installing them on a stock-height vehicle may result in the shock bottoming out and sustaining internal damage.
