MUNCIE SYNCHRO HUB - LATE STYLE For 1-2 or 3-4

The M-090-001 Muncie 4 speed synchronizer hub is an updated nirided 8620 alloy hub. Race proven for durability, the hub splines will not distort under load or collapse when using Torque locking sliders.  These are 1" wide hubs and use late style synchro rings. We recommend using these hubs in earlier 1963 to 1965 transmissions and using later stepped or shouldered synchro rings,
