3504-85 – End Yoke – 1350 Series – 1.312″ Splines Dia – 1.94″ Hub Dia

3504-85 is an End Yoke designed to connect the driveshaft to the transmission, transfer case, or differential in GM 8.5 applications. This yoke features a 1350 Series configuration, which is critical for ensuring compatibility with the corresponding U-joint. The 30 splines with a diameter of 1.312″ provide a robust interface that can handle the torque loads typical in performance and heavy-duty applications.

The dimensions of the 3504-85 are carefully engineered to accommodate the specific requirements of GM 8.5 setups. The hub diameter of 1.94″ allows for a secure fit while maintaining the necessary axial movement during suspension travel. This yoke also includes a through hole measuring 1.150″, which is essential for mounting and alignment purposes.

• Check spline engagement depth during installation.
• Verify phasing with the opposite yoke to prevent vibration issues.
• Ensure the spline count and diameter match the application before ordering.
• Use appropriate torque specifications when fastening to companion flanges.

In summary, the 3504-85 End Yoke is engineered for performance and reliability in GM 8.5 applications. Its specific dimensions and design features ensure it meets the demands of both everyday driving and more rigorous performance scenarios.
