Slimline spur gear upgrade for TRF801XT by Tamiya

The Tamiya 84042 - TRF801XT Lightweight Spur Gear is a precision part engineered to cut rotational mass on the TRF801XT chassis, improving drivetrain response. This spur reduces weight while maintaining strength, making it a practical upgrade for hobbyists focused on lap time gains.

Performance gains from a lighter spur gear

Fitting this lightweight spur to your TRF801XT helps the car accelerate quicker and feel more responsive under throttle. The reduced inertia improves corner exits and overall handling, giving drivers finer control when pushing for faster laps.

Fitment pointers and simple installation

Designed specifically for the TRF801XT, the gear drops in without modification. For best results, check gear mesh, keep bearings clean, and verify drivetrain alignment to prevent premature wear.

Will I need to change pinion gears after fitting this spur?

Not usually. Most setups retain the same pinion, but recheck gear mesh and verify clearance under load to avoid binding.

What motor types pair well with this spur gear?

This spur works with a wide range of brushless motors used in 1/8 on-road racing. Match motor timing and gearing to your track for optimal acceleration and top speed balance.

How should I maintain the lightweight spur?

Regularly inspect teeth and clean any debris, keep differential and pinion bearings lubricated, and replace if you notice wear to preserve drivetrain efficiency.
