The Dana Spicer 1300023 is a cluster gear. A cluster gear is a group of gears of different sizes that share one shaft and turn together as a single unit, so each gear can mesh with a different mating gear. Torque travels down the cluster shaft and out through whichever gear is meshed with the mainshaft, which is how a gearbox gets its different ratios. This is a genuine Dana Spicer part from Pro Gear and Transmission. Call us with your unit model to confirm proper fit before you order.
