Genuine FOX Fork Axles and Replacement Hardware for the Correct Front-Wheel Fit.
A fork axle needs to match the fork and the front hub exactly. Axle diameter, hub spacing, axle system and fork generation all matter, so this listing covers individual genuine FOX axle assemblies and small replacement parts for selected FOX and Marzocchi forks.
Options include 15QR, Kabolt, Kabolt SL, Kabolt X and pinch-axle systems, plus related nuts, hold-downs, bolts and hardware. These are not universal parts.

Before You Order
Confirm all of the following before choosing an axle:
- Fork model and model year
- Axle system: 15QR, Kabolt, Kabolt SL, Kabolt X or pinch axle
- Axle diameter and hub spacing
- Whether the fork has a Boost, non-Boost or a specific road/gravel hub standard
A 15 x 110mm Boost axle will not fit a 15 x 100mm hub, and a 20mm pinch axle is not interchangeable with a standard 15mm axle.
Use the serial number or four-digit product code in the FOX Bike Tech Help Center to identify your exact fork, then match the replacement part number to FOX’s parts information.
Our Thoughts
Axles can look very similar in a parts bin, but the wrong one can damage the fork threads, leave the hub poorly clamped or simply not fit. Check the part number on your existing axle if possible, and measure the hub standard rather than relying on the wheel size or fork stanchion diameter.
