Rancho RS9000XL 4.5″ Lift Shocks for 2014-2019 Ram 2500 4WD

Part Number: RS999048

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for heavy-duty applications. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to compensate for varying loads or terrain. Whether you are daily driving, towing a heavy trailer, or exploring off-road, this set is specifically configured to accommodate a 4.5-inch lift height while maintaining superior chassis control.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the driver can switch between a soft street ride and firm towing stability.
• Large Shock Body: A massive 2.75-in. diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance under high-cycle conditions.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob 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.

Will these shocks lift my Ram 2500?
No, these shocks do not create lift. They are specifically valved and extended to function correctly on vehicles that already have a 4.5-inch suspension lift kit installed.

What is the benefit of the large 2.75-inch body?
The larger body houses more fluid than standard shocks, which helps dissipate heat more efficiently, preventing “shock fade” during long towing trips or off-road excursions.
