TAMIYA T3-01 Aluminium Gear Box Plate T3038A by GPM  [T3038A]

Gearbox deck description

This aftermarket aluminium gearbox plate is designed for the TAMIYA T3-01 Dancing Rider and is listed as model T3038A. As a one-piece machined replacement for the factory plastic deck, it provides a firmer platform for the gearbox and a dependable surface for setup adjustments.

The product emphasises structural reinforcement and better tuning repeatability rather than modifying vehicle geometry. It locates in the T3-01 gearbox section and serves as a solid reference when setting spur alignment, pinion mesh and gearbox preload. Machined aluminium reduces unwanted flex at the gearbox mount points compared with the original polymer plate.

Fitting normally involves removing the original deck, moving any necessary bushings or standoffs, and securing the aluminium plate with the existing hardware. Confirm fitment with your T3-01 parts before finishing assembly and do not modify the plate unless you have the right tools and measurement checks.

Select this deck to reduce gearbox flex and achieve more consistent gear mesh when tuning the T3-01; verify all clearances after installation to protect gears and bearings.
