The 806806 is a Mack synchronizer upgrade kit, listed in the factory parts lists for the T2080B, T2130 / T2180, T310M and T313L / T318L transmissions. It bundles the low range hub, main drive gear, synchronizer assembly and sub-assembly, two housings, three support sleeves, a synchronizer clutch and two styles of synchronizer discs, eight of each, plus the screws, clamps, pins and spring sleeves. A synchronizer matches gear speed to shaft speed before the shift sleeve locks in, so a worn one grinds on shifts, resists the lever, or lets a gear pop out under load. Sold by Pro Gear and Transmission. Call us to confirm proper fit.
