Tamiya 54903 TB-05 Aluminum Spur Gear Holder OP-1903 - Performance Replacement Part  [54903]

Improve TB-05 drivetrain response with the Tamiya 54903 aluminum holder

Designed for the TB-05 chassis, the Tamiya 54903 Aluminum Spur Gear Holder reduces rotating mass and helps the drive system react faster to throttle changes while remaining a simple bolt-in swap.

Lower rotating mass for livelier acceleration

Using aluminium in this location reduces inertia on the spur, so the motor and drivetrain spin up with less resistance. That leads to more immediate acceleration from low speeds.

Robust anodized finish for regular use

The anodized surface gives added wear resistance and a clean look, helping the component hold up under routine running and servicing without losing reliability.
