HPI Bullet 3.0 Wheel Hex Adapter 14mm x 9mm - BMT010/14X9 by GPM  [BMT010/14X9]

Aluminium hex adapter for Bullet 3.0 wheel fitment

This RC-grade alloy hex adapter is made to suit original HPI Bullet 3.0 wheels and is supplied as a set of four pieces. It replaces the stock hex on MT and ST wheel variants to provide a firmer wheel to axle connection suitable for trail use and general bashing.

The adapter is specified at 14mm diameter with 9mm thickness to match the Bullet 3.0 wheel mounting face. In service it helps maintain wheel alignment and consistent runout, which makes tyre changes and handling tweaks more predictable on the same hub setup.

Installation is simple for models using original Bullet 3.0 fitment: remove the factory hex, slide the alloy adapter onto the hub, then mount and secure the wheel as normal. As this is an aftermarket accessory, confirm fit on your specific Bullet 3.0 wheel before extended running; do not trim hub surfaces unless clearance has been verified.
