Rancho RS5000X 0″ Rear Lift Shocks for US Postal FJ-9 2WD
Part Number: RS55113
Summary: The Rancho RS5000X series redefines entry-level performance by utilizing a sophisticated twin-tube gas pressurized design specifically tuned for the US Postal FJ-9. Engineered for durability and consistent street comfort, these shocks feature a unique cross-tuned valve system that balances low-speed stability with high-speed impact absorption. Whether navigating delivery routes or maintaining a fleet vehicle, these shocks provide a significant upgrade over stock units by reducing body roll and improving tire-to-road contact.
Features
- Cross-Tuned Technology: A specialized valve system provides a progressive damping curve to ensure smooth ride quality during daily operation.
- Gas Pressurized Twin-Tube: Nitrogen gas charge provides reduced aeration and foaming to ensure consistent damping performance under load.
- Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity.
- OE-Style Mounts: Precision-engineered mounting hardware provides a direct-fit installation to ensure a secure connection to the chassis.

Frequently Asked Questions
Will these shocks lift my vehicle?
No, these shocks are configured for a 0-inch lift and are designed to replace factory-length dampers without changing the vehicle’s ride height.
What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; even if the outer tube is dented by road debris, the inner working tube remains unaffected, ensuring you aren’t left stranded.

Based on the SKU configuration, this package includes 2 shocks for the rear of the vehicle.
