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

Hop-up 7075 motor mount for TB-03

The TB03-15 motor mount uses 7075 aluminium to replace the stock plastic unit on the Tamiya TB-03 chassis. Built as a direct hop-up replacement, it provides a more rigid motor seat and repeatable alignment to support steady pinion-to-spur contact and more predictable tuning.

This part is designed to use the TB-03's original mounting points and hardware. The 7075 alloy increases stiffness over typical stock materials, helping to limit flex during hard acceleration or braking and maintain consistent drivetrain engagement.

Installation requires basic tools: remove the factory motor mount, move the motor and spacers, locate the TB03-15 in place and secure with the chassis screws. Afterward fine-tune motor height and backlash to achieve quiet, efficient gear mesh.

Install this mount to reduce motor movement, firm up mesh settings and speed up the tuning process on TB-03 cars that keep the OEM mounting arrangement.
