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

Hex adapter for HPI Bullet 3.0 platforms

These four alloy hex adapters allow HPI Bullet 3.0 MT and ST nitro hubs to accept GPM EXO wheels Ex0503Front and Ex1003Front, sold under model BMT010/12X9. The 12mm hex and 9mm thickness are sized to match common EXO wheel hub interfaces.

The adapters provide reliable wheel mounting and correct wheel offset by replacing or extending the factory hex so the EXO wheels sit where intended on MT/ST nitro rigs. The alloy construction is chosen to maintain firm engagement and resist bending under normal RC usage.

Installation tips: clean hub and wheel mating surfaces, ensure the adapter orientation corresponds to the chosen wheel, check thread engagement and wheel-to-body clearance before running. The product is supplied as a 4pcs set to fit the mounting positions required by your wheel selection.
