Tamiya 54903 TB-05 Aluminum Spur Gear Holder OP-1903 - Lightweight Drivetrain Upgrade  [54903]

Refine TB-05 drivetrain performance with the Tamiya 54903 spur gear holder

If you want a tidy, effective upgrade for the TB-05 chassis, the Tamiya 54903 Aluminum Spur Gear Holder gives a noticeable drop in rotating mass and helps the car pick up speed more cleanly.

Reduced weight for quicker throttle response

Machined aluminum trims weight from the spur area, lowering inertia so throttle inputs translate to faster acceleration. Racers and club drivers looking for improved response will appreciate this simple swap.

Anodized surface for lasting use

The anodized coating adds surface protection and a neat finish, helping the holder resist wear from regular running. That means a stable drivetrain feel over many sessions.
