Fox 34 SL CSU

This assembly includes the crown, the steerer tube, and the upper stanchion tubes as a single, factory-pressed unit. It is designed to replace the entire upper structure of your fork, ensuring perfect alignment and structural integrity.

No, this CSU is specific to the 29-inch wheel size and 130mm travel configuration. You cannot use it to alter your fork's geometry or travel specifications, as the stanchion length and offset are fixed to these dimensions.

The crown, steerer, and stanchions are pressed together at the factory to ensure precise tolerances. Attempting to replace just the stanchions can compromise the structural rigidity and alignment of the fork, whereas replacing the full CSU restores the fork to its original factory performance.

This CSU is designed for specific Fox 34 SL models with a 1.5-inch tapered steerer and 34mm stanchion diameter. Before purchasing, verify your current fork's model year and specific damper type to ensure the steerer length and offset match your frame's requirements.

The Kashima coating is a proprietary surface treatment that reduces friction between the stanchions and the seals. This results in smoother, more responsive suspension travel and increased durability against wear compared to standard anodized finishes.
