Dana Spicer 170-4-2081-1X SPL170 Differential End Yoke
The Dana Spicer 170-4-2081-1X End Yoke is a genuine heavy-duty SPL170 Series differential end yoke assembly designed to connect the vehicle’s differential/pinion output to the driveshaft through the universal joint. Manufactured from high-strength steel and engineered to Dana Spicer specifications, this yoke provides the strength, precise spline engagement, and dimensional accuracy required for demanding Class 8 truck and heavy-duty driveline applications.
The 170-4-2081-1X features a 39-spline involute splined bore with a 2.024-inch major diameter and is designed for use with Spicer SPL170 driveline components. Its heavy-duty HR-style construction provides a secure connection between the differential and driveline while helping transmit engine torque reliably through the drivetrain.
Dana supplies this end yoke as an assembly and specifies that it includes the slinger/plug, helping provide the proper configuration for differential-end installation. Genuine Spicer yokes are engineered, manufactured, and validated to Dana’s OE requirements for fit, form, durability, and driveline performance.
