Summary: The Rancho RS9000XL series delivers professional-grade damping control for the US Postal FJ-8A.

Whether the vehicle is empty or at maximum capacity, this Tier 2 adjustable technology provides the versatility needed to maintain stability and ride quality.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can switch between a soft street ride and firm control for heavy-duty hauling.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during stop-and-go postal routes.
• Nitrogen Gas Charged: High-pressure nitrogen gas pressurized to 120 PSI provides a reduction in aeration and foaming to ensure consistent damping performance.
• Protective Boot: A heavy-duty liquid metallic finish and included bellows boot provide a shield against road debris and corrosion to ensure a long service life.
