Synchro Gear Teeth, 1st Gear 911 ’77-’86, Asymmetrical Tooth Point, One Slot in Hub (for use with assymetrical shift sleeve). These synchro hubs or “dog rings” feature our exclusive differential heat-treatment process which produces very hard and wear resistant engagement teeth with softer internal splines to help protect and extend the life of your expensive free gear nose. Manufactured by us right here in Colorado from only the finest domestically produced alloy steel. The factory never sold these as seperate parts and most of the “original manufacturer” or “o.e.m.” parts out there are actually made in Taiwan, and re-labeled as “German”.
