355055 Center Diff Spur Gear 41T
Large bevel gears for center differential are 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 gears are then laser engraved for easy and instant recognition.
Our special heat treatment makes the gear very hard and strong not only on the surface but also in the core, thus give the gear an extraordinarily-long lifespan with very low wear comparing to standard gears.
