COUPLING SHAFT

The Dana Spicer 819039-4012R is an 1810-series coupling shaft, designed for heavy-duty drive line applications. This component provides critical power transmission between drivetrain components. It features a robust steel construction with a 4.59-inch diameter tube, engineered for demanding vocational environments.

The shaft measures 40.3750 inches in tube length, with a collapsed CL yoke to CL yoke length of 51.9734 inches. It is specifically designed for 1810 series specifications and is frequently referenced for heavy-duty commercial vehicles, including applications for Freightliner and Paccar platforms.

This component is typically installed by professional technicians in heavy-duty truck shops. It is essential to ensure the exact length and series requirements match the specific chassis serial number, as these parts are often application-specific to commercial vocational setups.

Compatibility is generally determined by chassis-specific engineering requirements rather than standard consumer vehicle trims. It is common for this part to be cross-referenced to specific manufacturer part numbers such as Freightliner A09-30120-520 and Paccar E05D181HC9000C1320.
