Performance Boost from the XRAY 305912 Narrow Pinion

The XRAY 305912 Narrow Pinion Gear is made for RC drivers wanting precise, long lasting components. Machined from aircraft grade duraluminum, this pinion is 1.5mm thinner and about 25% lighter than standard alternatives, helping cut rotating mass for quicker spool up.

Tight Concentricity via Precision Machining

Produced on XRAY precision gear equipment, the narrow pinion delivers excellent concentricity. Each unit receives detailed machining, chamfered edges and a hardcoat finish to preserve geometry and resist wear during repeated runs.

Smoother Mesh with Spur Gears

Engineered to mesh cleanly with a wide range of spur gears and particularly well with XRAY spurs, this pinion helps reduce throttle on/off clatter for quieter, more predictable drivetrain behaviour. That makes it a useful upgrade for race setups focused on consistency.
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 the XRAY 305912 fit my T4 2017 chassis?

Yes, the 305912 narrow pinion is produced to match T4 2017 Specs and fits compatible T4 gearboxes without modification when proper gear mesh is set.

Does the hardcoat change gear performance?

The hardcoat improves surface hardness and wear resistance while keeping the original gear profile, so durability increases with little or no negative effect on mesh quality.

Any setup tips for installing a narrow pinion?

Check gear mesh with a thin shim or paper method, ensure the motor mount is secure, and recheck under load after a brief run-in to confirm smooth engagement.
