COUPLING SHAFT

The Dana 810663-4705R is a 1760 series ReadyShaft™ driveshaft assembly designed for heavy-duty commercial vehicle applications. This driveshaft features a 4.09-inch tube diameter with a 0.180-inch wall thickness. It includes pre-installed universal joints and is engineered to precise dimensional specifications for critical driveline performance in commercial environments.

The assembly is built with a tube length of 47.1563 inches (1197.77 mm). Key measurements include a CL Yoke to CL Bearing distance of 52.2074 inches (1326.07 mm) and a collapsed CL Yoke to CL Yoke length of 58.4082 inches (1483.57 mm). The unit is phased at 0 degrees, ensuring balanced operation for heavy-duty requirements.

Professional installation is required, and users should verify that the specified tube dimensions and lengths match the required driveline geometry of their specific heavy-duty vehicle before ordering. This part is a complete assembly, reducing the need for field welding or separate component balancing.

As a high-spec commercial component, fitment is based on the dimensional requirements of the driveline rather than standard consumer vehicle makes and models. Proper identification requires comparing these physical dimensions against existing shaft measurements or the OE part number being replaced.
