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

Precision aluminium hex for Bullet 3.0 wheels

This precision aluminium hex adapter is engineered for original HPI Bullet 3.0 wheels and is supplied as a set of four components. It serves as a direct aftermarket replacement hex for MT and ST wheel variants, providing a rigid wheel to axle interface suitable for serious hobby use.

The adapter is specified at 14mm diameter with a 9mm face thickness to align with the Bullet 3.0 wheel mounting face. Proper fitment helps maintain consistent wheel alignment and reduce runout variability, which benefits handling setup and reliable tyre swaps on a single hub configuration.

Installation follows standard procedure for Bullet 3.0 fitment: remove the OEM hex, locate the alloy adapter on the hub face, and secure the wheel using the original method. As an aftermarket upgrade, verify wheel clearance and fit before prolonged running and avoid altering hub faces unless you have confirmed the modification is safe.
