HPI Bullet 3.0 Hex Adapter for MT ST Wheels 14mm 9mm - BMT010/14X9 by GPM  [BMT010/14X9]

Bullet 3.0 aluminium hex upgrade

This alloy hex adapter has been produced for use with original HPI Bullet 3.0 wheels and is supplied as a set of four. It offers a direct replacement hex interface for MT and ST wheel styles, giving a more positive connection between wheel and axle for everyday trail running and casual bashing.

The adapter measures 14mm in diameter with a 9mm face thickness to align with the Bullet 3.0 wheel mounting surface. It helps keep wheel alignment and runout consistent, which is useful when swapping tyre types or tuning suspension on the same hub setup.

Fitting is straightforward on models that retain the Bullet 3.0 wheel fitment: remove the original hex, fit the alloy adapter onto the hub, then mount and tighten the wheel as usual. As with all aftermarket parts, verify clearance and fit on your specific wheel before extended use; avoid hub trimming unless you have confirmed safe clearance.
