Fox Suspension 38 CSU

No, this specific CSU is designed for the Fox 38 model with 180mm of travel and a 44mm rake. You must match the travel and offset specifications of your current fork to ensure proper geometry and handling.

Yes, this is a complete crown, steerer, and upper tube (CSU) assembly. The stanchions are pressed into the crown at the factory, so it arrives ready to be installed into your existing lower legs.

While this CSU is built for 180mm travel, changing your fork's travel is primarily determined by the air spring assembly inside the lower legs, not the CSU itself. Replacing the CSU will not inherently change your fork's travel, but you should ensure the stanchion length matches your intended setup.

Replacing a CSU is a significant service procedure that requires specialized tools, including a fork seal driver, a torque wrench, and the correct suspension fluids. If you are not comfortable performing a full fork teardown, it is highly recommended to have a professional mechanic handle the installation to ensure safety and proper function.

The steerer tube is permanently pressed into the crown, and the stanchion tubes are pressed into the crown as well. Because these components are structurally bonded at the factory to maintain precise tolerances, they are not serviceable individually.
