FAQ

Precision Narrow Pinion Crafted by XRAY

The XRAY 305989 Aluminum Narrow Pinion Gear is built for drivers who value exact gear timing and reliable performance. Produced with refined machining techniques, it achieves very fine tolerances and superior concentricity to deliver steady, low-noise operation.

Strong Yet Lightweight Duraluminum

Forged from aircraft-grade duraluminium, this pinion combines strength with reduced mass, being about 1.5 mm thinner and around 25% lighter than typical pinions. That weight saving helps the drivetrain spin up faster and improves overall efficiency.

Durable Hard Coating and Smooth Running

A controlled hard-coating process increases surface durability and helps the gear retain its profile over longer use. Chamfered teeth and a proper break-in finish ensure consistent engagement with spur gears, and it particularly complements XRAY spur gears by keeping throttle noise down.

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.

Is the XRAY 305989 suitable for club racing?

Yes, its tight tolerances and lightweight profile make it a solid choice for club-level racing where smooth, predictable power delivery matters.

Any special break-in needed for longevity?

A short running-in period under light load helps seat the chamfered edges and maximise quiet engagement; follow your normal gear mesh routine.
