HPI Baja Spur Adaptor BJ115 Alloy Upgrade by GPM  [BJ115]

Spur adaptor engineered for HPI Baja use

This alloy spur gear adaptor is a replacement component intended for HPI Baja platforms. It acts as the interface between the spur gear and the gearbox or motor mount, delivering a matched mounting surface and keeping drive components in alignment.

Fitment concentrates on correct seating and axial alignment: confirm the adaptor seats flush on the spur gear hub, secure it using your original fastening method, and check mesh and backlash after fitting. Supplied as a single pcs unit, it replaces worn or damaged adaptors without changing motor or spur gear specifications.

Fit BJ115 when you need a like-for-like replacement to maintain correct spur mounting on HPI Baja buggies.
