Precision lightweight spur for the TRF801XT from Tamiya

The Tamiya 84042 - TRF801XT Lightweight Spur Gear is a precision component made to cut rotating mass on the TRF801XT chassis, enhancing drivetrain efficiency. It offers a straightforward weight-saving upgrade for drivers focused on handling and acceleration.

Why a lighter spur improves driveability

Reducing the mass of the spur lowers inertia in the gear train, which translates to crisper throttle response and better cornering exits. The result is a more controllable car when lap times matter.

Fitment details and maintenance tips

Specifically produced for the TRF801XT, this spur fits without extra work. For longevity, maintain proper mesh, keep drivetrain parts clean, and inspect the gear after impacts.

Does this spur require special pinion alignment?

No special alignment is needed beyond standard pinion-to-spur mesh checks; set a correct clearance and secure both gears firmly.

Is noise increased with a lightweight spur?

Noise levels should remain similar; any change is typically minor and depends more on mesh and bearing condition than on spur mass alone.

Can I use this spur for practice and competition?

Yes, it is suitable for both practice and race days provided you perform routine checks and replace the gear if significant wear appears.
