Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an external 9-position knob located on the shock body that can be turned by hand to increase or decrease damping resistance.

Do these shocks provide any lift to my FJ-8A?
No, these shocks are configured for 0 inches of lift and are designed to replace the factory-length dampers at stock height.

Why is there a “Lower Mount: Upper” listed in some data?
That is a data error; these shocks utilize a standard OE-style loop mount to ensure a direct-fit installation on the US Postal FJ-8A.
