Description

The Dana Spicer 810663-3708R is an inter-axle coupling shaft designed for use with the D190-Series tandem drive axle assemblies. This component is critical for power transfer between the forward and rear drive axles in heavy-duty truck applications.

As a high-precision driveline component, it is engineered to meet original equipment standards for material strength and spline tolerances, ensuring reliable operation under high torque loads.

Installation should be performed by a qualified technician during a tandem axle service or rebuild. It is highly recommended to verify the specific Dana/Spicer axle Bill of Materials (BOM) or serial plate to ensure this coupling shaft matches the existing drive assembly configuration. Proper lubrication and spline alignment are required during assembly.

Compatibility is determined by the axle model and configuration, specifically the D190-Series. This part fits applications utilizing the corresponding D190 tandem drive axle, common in various heavy-duty commercial vehicles. Always cross-reference with the vehicle's specific axle specification.
