XRAY 385742 42T Spur Gear Upgrade for M18

The XRAY 385742 42T Spur Gear is a practical performance upgrade for M18 models prepared with graphite chassis, designed to boost acceleration and improve lap consistency. It suits drivers focused on reliable race performance.

Performance Characteristics

The 42-tooth configuration modifies drive ratio to give stronger launch and mid-corner acceleration compared with stock gears, aiding drivers on tighter circuits where exit speed matters most.

Fitting and Adjustments

Although intended for graphite chassis, the spur can be used on composite vehicles if mesh and shimming are correctly set. Check the download area for comprehensive fitting instructions and recommended adjustments.
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.

Can I pair this spur with aftermarket pinions?

Yes, aftermarket pinions can be used but choose sizes carefully to match track layout and motor characteristics for best results.

Will the 42T place extra load on the motor or drivetrain?

It changes acceleration characteristics which can slightly alter motor load; monitor motor temperature and adjust gearing or motor settings if loads increase.

Are spare parts interchangeable across M18 variants?

Many M18 drivetrain parts are shared, but always verify part numbers and fitment before swapping spurs or hardware between variants.

Any tips for first-time installation?

Start with conservative pinion selection, set precise mesh, check for binding, and run a short break-in before full race use.
