Dana Spicer 6.3-4-211X 1760-Series End Yoke Assembly
The Dana Spicer 6.3-4-211X End Yoke Assembly is a genuine Spicer pinion-shaft or differential end yoke designed for select 1760-series heavy-duty commercial driveline applications. It mounts to a compatible 46-spline shaft and provides the connection between the axle or transmission output and a 1760-series universal joint.
Manufactured from heavy-duty steel, the 6.3-4-211X features a 2.374-inch spline major diameter, a 3.250-inch hub diameter, and Dana’s BP bearing-plate-style universal-joint retention configuration. The complete assembly includes the associated slinger or plug, helping protect the seal area and maintain the intended OE installation dimensions.

The Meritor 176N4211X/176N-4-211X is the most commonly published non-Dana interchange. All alternatives should still be verified by spline count, spline diameter, hub dimensions, yoke style and application before installation.
Dana’s end-yoke catalog identifies:
- 6.3-4-101 — underlying yoke component
- 231179 — associated slinger or plug
- 5-407X — standard 1760-series universal-joint kit
- 5-677X — related 1760-series universal joint for applicable mixed configurations
The 6.3-4-101 is a component-level reference and should not automatically be treated as the same complete assembly because the 6.3-4-211X includes the slinger or plug.
