Features

• Large Shock Body: A massive 2.75-inch diameter body provides increased fluid capacity to ensure cool operation and consistent performance during heavy-duty use.
• Nitrogen Gas Charged: High-pressure nitrogen gas pressurized to 120 PSI provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal durability against road debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position manual 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 any lift to my truck?
No, these shocks are configured for a 0-inch lift height and are designed to replace factory-length shocks without changing the vehicle’s ride height.

What is the benefit of the large 2.75-inch body?
The larger body houses more oil than standard shocks, which helps the shock stay cooler under stress, preventing the “fading” or softening felt during long drives or heavy hauling.
