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

Front and rear alloy gearbox for Bullet 3.0 and WR8

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 component focuses on mechanical fit and serviceability: mounting points and interface surfaces correspond to the original gearbox layout to allow reuse of existing spur gear, pinion, and associated fasteners. Use basic teardown and reassembly steps when replacing the module, verify mesh and alignment during reinstallation, and check driveline rotation before running.

For tuning and maintenance, this alloy assembly serves as a like-for-like spare part for routine repairs and drivetrain inspections. It does not include internal bearings or gear hardware beyond the boxed housing unless specified by the supplier, so confirm included items before starting work.

Keep this alloy gearbox housing set on hand to replace damaged housings or to support regular servicing of WR8 and Bullet 3.0 nitro builds, and verify what hardware is included on arrival to match your chassis.
