Summary: The Rancho RS9000XL series provides unparalleled control for your classic GMC C3500.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect balance between street comfort and heavy-duty towing performance.
• Large Diameter Body: A 2.75-inch tri-tube body provides increased fluid capacity to ensure cooler operation and consistent damping under high-stress conditions.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure immediate response and fade-free performance.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a red 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.

Will these shocks lift my GMC C3500?
No, these shocks are configured for a 0-inch lift and do not provide lift height; they are designed to replace factory-length dampers while offering superior control.

What is the benefit of the tri-tube design?
The larger tri-tube body allows for a greater oil capacity, which helps dissipate heat more efficiently than standard shocks, preventing performance fade during heavy use.
