A tidy, strong replacement axle for FOX 40 downhill forks.
The Burgtec FOX 40 Front Axle replaces the standard axle with a clean, leverless design. Machined from 7075 aluminium, it provides a strong and lightweight option for downhill and bike-park bikes fitted with a FOX 40 fork.
A 6mm hex fitting handles normal installation and removal, while a secondary 8mm fitting provides a useful backup if the smaller interface becomes damaged.
FOX 40 Compatibility
Burgtec states that this axle fits all generations of FOX 40 forks. Compatibility is determined by the fork rather than the bike or front hub alone, so it should not be treated as a universal replacement for every 20mm front axle.
Check that your fork is a genuine FOX 40 and compare the existing axle before ordering. If you are unsure which fork or axle standard is fitted, contact our Christchurch team for advice.
7075 Aluminium Construction
The axle is CNC-machined from 7075 aluminium, providing a useful balance of strength, stiffness and low weight. Its leverless shape also creates a clean finish around the fork dropout and avoids having an external lever that can catch on vegetation or equipment.
Dual Hex Fittings
The primary 6mm hex fitting is used for regular wheel removal and installation. A secondary 8mm hex interface provides a backup removal option if the 6mm fitting becomes rounded or damaged.
Always use a correctly fitting hex key and follow the tightening instructions supplied with your FOX fork. The backup fitting does not remove the need for correct installation or justify overtightening the axle.

Our Thoughts
This is a straightforward upgrade for riders wanting a clean, colour-matched axle for a FOX 40. The leverless design looks tidy and the secondary 8mm fitting is a practical feature if the main hex interface is ever damaged.
Use a good-quality hex key and observe the correct FOX tightening procedure. Most damaged axle fittings result from worn tools, incomplete tool engagement or excessive torque rather than normal riding.
