Part Number: RS999056

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping control, specifically engineered to handle the demands of heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy towing or off-road stability. This versatility ensures that your Dodge Ram 3500 maintains optimal chassis control regardless of payload or terrain. Configured for 4-inch rear lift heights, these shocks provide the necessary travel and damping force to complement your lifted suspension system.

Features

• 9-Position Tuning Knob: Manual damping adjustment provides 400% more control variation than standard shocks to ensure custom-tailored ride quality for any load.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides consistent valving response to ensure reduced aeration and foaming.
• Polyurethane Bushings: High-density polyurethane material provides improved durability and pivot response to ensure long-term service life in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body. Simply turn the dial to a lower number for a softer ride or a higher number for increased firmness and control.

Will these shocks provide my truck with a 4-inch lift?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that have already been equipped with a 4-inch rear lift kit.

Are these shocks suitable for heavy towing?
Yes, the RS9000XL is ideal for towing. By increasing the setting on the adjustment knob, you can provide the extra damping required to control trailer sway and rear-end porpoising.
