Dana Spicer 127645 Differential Side Gear
The Dana Spicer 127645 Side Gear is a heavy-duty differential output side gear used in select Dana/Spicer tandem-drive axle assemblies. It transfers torque from the differential case to the axle shaft while allowing the differential gearing to accommodate speed differences between the drive wheels.
The 127645 is identified as a 14-tooth, 34-spline side gear and is associated with Dana/Spicer 344, 404, 405, and 454-series axle applications.
