HPI Bullet 3.0 MT/ST Hex Wheel Adapter 12x9mm by GPM BMT010/12X9  [BMT010/12X9]

Wheel adapter for HPI Bullet 3.0

This is a purpose-made RC-scale hex wheel adapter intended for HPI Bullet 3.0 MT and ST nitro platforms, produced by GPM as part number BMT010/12X9. The set contains four pcs designed to interface HPI wheel hubs with GPM optional EXO wheels Ex0503Front and Ex1003Front using an alloy hex hub of 12mm outer diameter and 9mm thickness.

The adapter's role is mechanical compatibility and wheel positioning: it replaces or extends the factory wheel hex so the EXO wheels seat correctly and maintain intended offset and clearance on MT/ST nitro setups. Because it is an alloy part the focus is on maintaining a firm fit between wheel and hub while resisting deformation under normal RC driving loads.

Installation considerations: verify wheel bore and hub mating surfaces are clean and free of paint or debris, confirm the adapter orientation matches the wheel model, and check thread engagement and wheel clearance on the suspensions and body before first run. This component is sold as a 4pcs set to cover both sides of a vehicle's front or rear mounting positions as required by the wheel configuration.
