XRay Active Center Diff Spur Gear 42T

This is a replacement XRAY 42 Tooth Active Center Diff Spur Gear, and is intended for use with the XRAY XB808, and XB808 09 Spec 1/8 buggies. This 42-tooth large bevel gear is machined from special HUDY steel material which has been specially developed for gear-type products, additionally hardened and precision ground to fit the tightest tolerance requirements for perfect fit with the diff outdrives. The gears are individually machined on a precision German gear machine and every gear is individually tested, inspected, and run in. The diff gear is then laser engraved with "Active 42T" for easy and instant recognition.

XRAY's special heat treatment makes the gear very hard and strong not only on the surface but also in the core, thus giving the gear an extraordinarily-long lifespan with very low wear comparing to standard gears.
