High precision pinion built for XRAY RX8 performance

Serious racers choose the XRAY 348428 pinion for its blend of accurate tooth geometry and robust construction. This 18T aluminum pinion for the RX8 series is engineered to provide consistent power transfer and reduced drivetrain vibration at speed.

Swiss 7075 T6 construction with tough finish

Manufactured from Swiss 7075 T6 aluminum, the gear keeps weight low while offering a high strength-to-weight ratio. A hard coated surface helps resist scoring and wear so the gear lasts through repeated race conditions.

Built for drivetrain efficiency

Whether replacing worn parts or upgrading for tighter tolerances, this pinion improves mesh consistency and reduces friction in RX8 drivetrains. The 18-tooth count is optimised for common gearing setups used in competitive classes.

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.

Will this pinion fit other XRAY models?

This pinion is made for the XRAY RX8 series. Other XRAY models may use different shaft diameters or pitch, so check your model specifications before fitting.

How should I maintain the 7075 pinion?

Clean debris after runs and inspect teeth for nicks. Lightly lubricate mating gears as recommended, and replace the pinion if you spot excessive wear or burrs.

Can I change gear ratios with this 18T unit?

Yes, swapping tooth counts alters final ratio. When changing the pinion, check mesh and ensure the spur gear and motor pinion are compatible to avoid binding.
