The Dana Spicer Coupling Shaft, part number 810663-4304 or 8106634304, is a genuine Spicer driveline component designed for heavy-duty truck applications. Coupling shafts serve as an intermediate drive shaft section, connecting driveline segments where a standard full-length shaft is not practical — common in tandem-axle and multi-piece driveline configurations. This part is sold individually (unit of measure: each) and is sourced directly from Dana Spicer. Pro Gear and Transmission carries genuine Spicer driveline parts. Not sure this is your part?
