Give your TB-05 crisper starts with the Tamiya 54903 spur gear holder

The Tamiya 54903 Aluminum Spur Gear Holder is a direct-fit upgrade for TB-05 setups. It trims mass at the spur assembly to help the car accelerate more responsively from standstill.

Compact, lightweight construction

Aluminium construction cuts down rotating weight, improving how quickly the drive system spins up. This is especially useful for tight courses where quick launches matter.

Hard-wearing anodized coating

An anodized finish helps protect the holder against scuffs and corrosion, keeping the mounting area stable through regular running and maintenance cycles.

Can I reuse bearings from the stock holder?

Yes, bearings can usually be transferred from the original holder. Inspect them for play or damage before reuse to avoid drivetrain issues.

Will it change top speed or just acceleration?

The main effect is improved acceleration and throttle feel. Top speed is governed more by gearing and motor power than by the spur holder alone.

What tools are needed for fitment?

Basic hand tools like hex drivers and a small screwdriver are sufficient. A torque driver is useful to avoid over-tightening small screws.
