TB-03 7075 Aluminium Spur Gear Adaptor TB03-14 by 3Racing  [TB03-14]

7075 Alloy Spur Adaptor for TB-03

This spur adaptor is made for the TB-03 chassis and is identified as TB03-14. Fabricated from 7075 aluminium, the part is intended as a direct replacement for the factory adaptor to stiffen the spur mounting and cut down play in the drive system.

Installation on TB-03 cars that accept the common spur adaptor shape is straightforward. The adaptor locates to the same spur interface and preserves the original layout, so installation focuses on seating the unit correctly and confirming gear mesh and alignment instead of changing mount positions.

During tuning and regular service the aluminium adaptor helps maintain consistent mesh after multiple runs and when the drivetrain sees increased stress compared with softer replacements, making it useful when refining on-track behaviour.
