HPI Bullet 3.0 / WR8 Alloy Front and Rear Gear Box BMT012 by GPM  [BMT012]

Alloy front and rear gearbox housings for service use

This alloy front and rear gear box set is a direct-fit RC-scale replacement intended for HPI Bullet 3.0 MT and ST nitro platforms. It is supplied as a single set and matches the service role of replacing worn or damaged gearbox modules on compatible WR8 and Bullet 3.0 chassis.

The unit emphasises correct mechanical interfaces: mounting locations and bearing seats reflect the original gearbox so spur gear, pinion and existing fasteners can be retained where compatible. When installing, follow teardown guidance, set proper gear mesh, and check for smooth driveline rotation before running the model.

Used for routine maintenance and tuning, this alloy housing set provides a replaceable casing for inspections and repairs. Note that internal bearings, gears or small hardware might not be included, so confirm the contents with the supplier prior to starting work.

This alloy gearbox housing set is useful for replacing damaged housings or holding spare parts for WR8 and Bullet 3.0 nitro projects; always verify included components match your chassis requirements.
