Slim, Hardcoated Pinion for Competitive Use

The XRAY 305918 Narrow Pinion Gear is aimed at drivers who want a lighter gearbox component without losing toughness. Made from aircraft duraluminum, it is 1.5mm narrower and around 25% lighter than standard pinions, making it popular for weight-conscious setups.

Accurate Cutting and Protective Hardcoat

Cut on a precision gear machine to tight tolerances, this XRAY pinion offers excellent balance and concentricity. After chamfering the teeth, a hardcoating is applied to improve wear resistance. When paired with XRAY spur gears the gearset runs smoother and with less throttle noise.

Compatibility with T4 Series Cars

Specifically compatible with T4 Series models including the T4 2017 Specs, the XRAY 305918 Narrow Pinion Gear works as a direct upgrade or replacement to maintain consistent gear engagement and track-ready performance.
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.

Will using a narrower pinion affect durability?

The material and hardcoating are chosen to preserve strength despite the narrower profile, but correct mesh and alignment remain important to avoid premature wear.

How do I confirm the pinion fits my motor shaft?

Check the pinion bore and set screw size against your motor shaft specifications. If needed, use the proper adapter or select the matching pinion variant.

Any tips for reducing gear noise after installation?

Ensure accurate mesh with a small clearance, secure the pinion firmly, and run the drivetrain briefly to let parts seat before rechecking the mesh.
