XRAY 385742 Spur Upgrade for M18 Performance

The XRAY 385742 42T Spur Gear offers a performance boost for M18 cars running graphite chassis, focusing on improved acceleration and steadier drive under load. It is aimed at drivers who want measurable gains on race day.

Acceleration Versus Handling Balance

The 42-tooth design changes the gear ratio to provide stronger exit acceleration while keeping predictable handling through corners. This helps close gaps on technical sections of the track.

Installation Tips for Chassis Fit

Primarily designed for graphite chassis, the spur can be fitted to composite M18 variants if mesh and mounting are adjusted. See the download area for mounting steps and alignment advice to avoid premature wear.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which pinion sizes work well with a 42T on the M18?

Pinion choice depends on track layout; smaller pinions help tight technical circuits while larger pinions raise top speed on fast tracks. Tune by lap times rather than numbers.

Is this spur suitable for carpet and asphalt surfaces?

Yes, the 42T can be used on both surfaces, but you may need to alter pinion size and tyre choice to match grip and track character.

Will I need special tools to fit this gear?

No specialised tools are required; standard RC tools and a good mesh gauge are sufficient. Follow the download area instructions for precise setup.

Is the 42T compatible with stock differential settings?

It works with stock diff setups but you may need to adjust diff preload or oil weight to restore handling balance after changing gearing.
