MTX-4 54T Delrin Spur

This is a spur gear made for the Mugen Seiki MTX-4 chassis, listed as MTX4-0854/V3 from 3Racing. The Delrin construction lowers mesh friction and is cut to a 0.8 pitch for consistent engagement with compatible pinions.

Swap in this spur to replace worn teeth or to fine-tune drivetrain efficiency for sharper throttle control on technical circuits. Delrin works well against typical pinion materials and can help maintain smoother driveline behaviour during practice and races.

Fit notes: confirm correct pinion spacing and tooth contact, inspect gearbox washers and bearings for play, and re-check mesh after a short break-in to ensure reliable operation.

Does this require a specific gearbox shim?

No special shim is required beyond standard MTX-4 gearbox spacing; adjust the pinion position and use existing shims or washers to get the correct mesh.

Is this suitable for high-power setups?

Delrin handles moderate loads well but inspect for accelerated wear on very high-torque brushless setups and consider metal options if you see rapid degradation.

How often should I inspect the spur?

Check the spur after every few race sessions for wear, and replace once teeth show rounding or material loss to avoid damaging the pinion.
