Fox 38 CSU Assembly

This assembly is designed specifically for the Fox 38 chassis with a 44mm offset and 1.5-inch tapered steerer. Before purchasing, verify your current fork's travel, axle spacing, and steerer tube requirements to ensure an exact match.

The signature gold Kashima coating is a proprietary surface treatment designed to reduce friction between the stanchions and seals. This results in a smoother suspension feel, better small-bump sensitivity, and increased durability over time.

Yes, this is a complete Crown-Steerer-Upper (CSU) assembly. The steerer tube is factory-pressed into the crown, so it arrives ready for installation without needing specialized pressing tools.

While this assembly is built for 180mm of travel, changing your fork's travel usually involves internal air spring adjustments rather than replacing the CSU. This part is primarily intended to replace a damaged or worn crown and steerer, not to alter your fork's travel geometry.

Replacing a CSU is a significant service procedure that requires removing your fork lowers and damper internals. If you are not comfortable with advanced suspension maintenance and have the necessary tools, we strongly recommend having a qualified bike mechanic perform the swap to ensure safety.
