TB-03 Precision 7075 Motor Mount TB03-15 for Tamiya by 3Racing  [TB03-15]

Precision 7075 motor mount for TB-03

The TB03-15 is a precision 7075 aluminium motor mount tailored for the Tamiya TB-03 chassis as a hop-up replacement. It focuses on firm motor positioning and consistent alignment to keep pinion-to-spur mesh repeatable during setup and track use.

Replacing the stock plastic mount, this aluminium part uses the TB-03's original mounting holes and hardware. The 7075 construction delivers greater stiffness than factory material, limiting flex under load and helping the drivetrain keep reliable gear engagement through acceleration and braking.

Installation is suitable for a hobbyist with common tools: remove the old motor mount, transfer the motor and any spacers, seat the TB03-15 and secure with the chassis screws. Afterwards check mesh and backlash, then make small adjustments to reduce noise and ensure smooth gear engagement.

Fit this mount to tighten the motor interface, stabilise mesh and simplify gear tuning on TB-03 cars that retain the stock mounting layout.
