XRAY 305979 Narrow Alloy Pinion 29T/64  [XR-305979]

Precision Machined Narrow Pinion

Upgrading with the XRAY 305979 Aluminum Narrow Pinion Gear gives noticeable reductions in rotating mass without sacrificing durability. The pinion is made from aircraft-grade duraluminum and is 1.5mm thinner and roughly 25% lighter compared to standard pinions, which helps with quicker throttle response.

Quality Production and Protective Finish

Manufacture uses a specially-modified precision gear machine to secure tight runout and accurate tooth geometry. All edges are chamfered and a hardcoat finish is applied to improve longevity. Matched to the correct spur gear, especially XRAY spur gears, the accurate machining reduces drivetrain noise for smoother power delivery.

Ready for Racing and Upgrades

Targeted at competitive hobbyists, the XRAY 305979 installs easily and delivers consistent, reliable operation. Its trimmed weight helps with handling and transient performance, making it a useful upgrade for both maintenance and performance tuning.
