Dana Spicer 131437K 1710 Series Half-Round Differential End Yoke Assembly
The Dana Spicer 131437K Yoke Assembly is a genuine Spicer 1710 Series half-round differential end yoke kit designed for select Dana heavy-duty axle applications. It mounts to the differential pinion shaft and provides the connection point between the axle input and the driveshaft universal joint.
Dana identifies the 131437K as a differential end yoke assembly for Spicer axles. It uses a 2.544-inch, 49-spline involute bore and is configured for a 1710 Series half-round universal joint. The kit is associated with Dana yoke assembly 5008453 and includes the required 131095 pinion nut for Spicer axle applications.

Components and Cross-References
Dana catalogs associate the 131437K with:
- 5008453 – previous yoke assembly number
- 6-4-08453-1X – updated/replacement end yoke number
- 6-4-10291-1 – production reference / bare yoke configuration
- 5008437 – slinger
- 131095 – pinion nut
Dana’s end-yoke catalog notes that 5008453 was replaced by 6-4-08453-1X, and that the 131437K configuration consists of the half-round yoke together with the 131095 nut for Spicer axle use.
Compatible U-Joint
The 131437K is designed for a 1710 Series half-round U-joint with approximately:
- 1.938-inch bearing caps
- 6.094-inch span
Common compatible Spicer U-joint kits include the 5-675X, depending on the specific driveline configuration.
Features & Benefits

Installation Note
The 131437K is specifically a half-round 1710 Series yoke. It should not be confused with the similar 131442K, which uses the same 49-spline shaft dimensions but a full-round/bearing-plate style configuration. Dana also lists related 1710 yokes with different centerline lengths and operating angles, so the original yoke number, spline specification, joint style, and axle application should be verified before ordering.
The Dana Spicer 131437K Yoke Assembly provides an OE-engineered solution for servicing compatible Dana heavy-duty axle assemblies requiring a 1710 half-round, 49-spline differential end yoke.
