Spicer 6.3-4-781X End Yoke 7 Inch Wide Universal Joint

Spicer 6.3-4-781X End Yoke Assembly for 1760-series universal joints is a steel end yoke built to the 1760 drive shaft family. The one-piece yoke features a 7-inch overall width across the ears, a geometrical specification that matches the 1760 BP-style end yoke configurations in Spicer catalogs. The bore is a 10-spline pattern designed to accept the corresponding 10-spline cross used in Dana Spicer 1760 joints, enabling secure torque transfer between driveshaft segments. This end yoke is intended for use as the terminal yoke on 1760-series drivelines, commonly found on heavy-duty trucks, construction and agricultural equipment, and off-road vehicles that rely on Spicer components for reliability in demanding service. The 6.3-4-781X designation identifies a specific yoke geometry and spline arrangement; users should verify spline count, bore size, and mounting style to ensure exact compatibility with their 1760-series cross and drive shaft tube. Sold as an end yoke assembly rather than a complete driveshaft, it is designed to be installed with the matching Spicer 1760-series joints and shafts, continuing to meet the performance requirements of Dana Spicer driveline systems.
