The XRAY 305725 pinion is machined from aircraft-grade duraluminum to strike a balance between low mass and structural strength. Made for the T4 2017 Specs series, this 25T / 48 pitch unit is engineered to run smoothly and hold up over repeated race sessions.
Manufacture takes place on XRAY precision gear machines to achieve tight tolerances. The chamfered tooth edges and hard-coated surface increase resistance to wear and help maintain consistent engagement under load.
Designed to pair cleanly with compatible spur gears, the XRAY 305725 helps reduce drivetrain noise and vibration. It is a straightforward swap when replacing worn pinions or dialing in gear ratios for track work.
