If you want to refine gearing on a T4 2017, the XRAY 305919 narrow pinion is a compact, tough option. Machined from aircraft duraluminum, this pinion is 1.5mm thinner and about 25% lighter than a standard pinion, giving reduced rotating mass while retaining strength.
Produced on a specially modified precision gear machine, this narrow pinion is made to exact concentricity standards. Every unit has chamfered edges and receives a hardcoat finish to resist wear and keep the gear running true for longer periods.
The XRAY 19T narrow pinion pairs well with compatible spur gears and is particularly quiet when matched to XRAY spur gears, reducing throttle on/off noise for a smoother drive feel.
