170-4-201-1X

END YOKE ASSY

This is a Spicer SPL170 series half-round end yoke assembly for the pinion shaft of a heavy-duty truck differential. It connects the driveshaft to the differential pinion, transmitting engine torque to the drive axles. The splined bore mounts directly onto the pinion shaft, and the half-round straps secure the universal joint. Replace this yoke when the splines are worn, the yoke ears are damaged, or to address driveline vibration and oil seal leaks.
