TAMIYA T3-01 Dancing Rider Aluminum Gear Box Deck by GPM T3038A  [T3038A]

Aluminum gear box deck overview

This aftermarket gear box deck is an RC-scale replacement part produced for the TAMIYA T3-01 Dancing Rider chassis, supplied under GPM part number T3038A. It is a single-piece aluminum deck designed to replace the stock plastic plate to provide a firmer mounting surface for the gearbox assembly and to offer a predictable platform for setup adjustments.

The part focuses on structural reinforcement and tuning stability rather than changing geometry. It fits into the T3-01 gearbox area and serves as a foundation when adjusting spur alignment, pinion mesh, and gearbox preload. The material choice—machined aluminum—helps reduce flex around the gearbox mount points compared with original polymer plates.

Installation typically involves removing the original deck, transferring any required bushings or standoffs, and securing the aluminum deck with the same mounting hardware. Because this is an RC accessory, confirm fitment with your T3-01 components before final assembly and avoid modifying the deck unless you have the correct tools and measurement references.

Use this deck when you want a stiffer gearbox mounting point for consistent gear mesh and chassis tuning on the T3-01 platform; verify alignment during installation to avoid undue bearing or gear wear.
