Rancho RS90000XL 0″ Front Lift Shocks for US Postal FJ-9 2WD

Part Number: RS999113

Summary: The Rancho RS90000XL series delivers industry-leading versatility for the US Postal FJ-9, featuring a globally recognized 9-position manual tuning knob. This Tier 2 adjustable shock allows drivers to instantly toggle between nine levels of damping to accommodate varying cargo loads or specific road conditions. By providing the ability to transition from a soft, compliant street ride to a firm, controlled setting, these shocks solve the compromise typically found in fixed-rate suspension components.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the vehicle is perfectly tuned for specific towing or hauling requirements.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas displacement provides a reduction in aeration and foaming to ensure consistent damping performance under load.
• Protective Boot: A durable poly-vinyl 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 on these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock; simply turn the dial to your desired setting without the need for tools.

Will these shocks lift my US Postal FJ-9?
No, these shocks are configured for 0-inches of lift and are designed to maintain the factory ride height while improving damping control.

What is the benefit of the larger 2.75-inch body?
The increased surface area and oil volume allow the shock to dissipate heat more efficiently, preventing “fade” during extended periods of operation.
