TAMIYA T3-01 Gearbox Reinforcement Deck T3038A by GPM  [T3038A]

Overview of the machined gear deck

This aftermarket machined aluminium deck is made for the TAMIYA T3-01 Dancing Rider and carries model number T3038A. As a single-piece replacement for the stock plastic plate, it provides a stiffer mounting surface for the gearbox and a consistent reference for setup work.

The component is focused on structural reinforcement and tuning reliability rather than changing suspension geometry. It mounts in the T3-01 gearbox area and acts as a stable foundation for adjusting spur alignment, pinion mesh and gearbox preload. Using machined aluminium reduces flex at the gearbox mount compared with the original polymer plate.

Fitment usually involves removing the original deck, transferring any required bushings or spacers, and attaching the aluminium deck with the same screws. Verify fit with your T3-01 components before final assembly and avoid making modifications unless you have proper tools and measurements.

Ideal when you need a firmer gearbox mounting point for stable gear mesh and reliable chassis setup on the T3-01; always check alignment and bearing clearance after installation.
