Rancho RS9000XL 0″ Lift Shocks for US Postal FJ-9 2WD

Part Number: RS999113

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for the US Postal FJ-9. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to tune your damping profile to match specific cargo loads or road conditions. Whether you require a firmer setting for heavy-duty service or a softer profile for improved street comfort, this nitrogen-charged solution delivers professional-grade performance and durability.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the vehicle is perfectly calibrated for varying load weights.
• Nitrogen Gas Charge: High-pressure gas displacement provides reduced aeration and foaming to ensure consistent damping performance during high-duty cycles.
• Large Diameter Body: An increased fluid capacity provides superior heat dissipation to ensure the shock maintains structural integrity under heavy use.
• Protective Boot: A heavy-duty poly-vinyl boot provides a shield for the shock rod to ensure debris does not compromise the internal seals.
