806807 is a synchronizer upgrade kit for the Mack T310M transmission, listed in our parts manual under the rear case components. It bundles a low range hub, a main drive gear, the synchronizer assembly and sub-assembly, two housings, three support sleeves, a synchronizer clutch and two sets of eight synchronizer discs, plus the screws, clamps, pins and spring sleeves. A synchronizer uses friction rings to bring the gear and shaft to the same speed before the dog clutch engages, and as those parts wear it matches speeds less effectively. Sold by Pro Gear and Transmission.
