3503-314 – Transmission Yokes – 1350 Series – 30/31 X 1.391 Splines – 1.685″ Hub Dia

The 3503-314 Transmission Yoke is a crucial component for any tech working on C6 FULL SPLINE applications. This yoke features a 1350 Series design, ensuring compatibility with various Ford and GM transmissions, including ZF5, Toploader, TKO-600, TKO-500, T56, T45, FMX, and E40D. Before installation, verify that the spline count matches your output shaft—this yoke has a 30/31 X 1.391 spline configuration.

When preparing to install the 3503-314, pay close attention to the hub diameter of 1.685 inches. This dimension is critical for ensuring a proper fit with the mating components. The slip yoke length measures 6.570 inches from the center U-joint to the end, which allows for necessary axial movement during suspension travel.

• Check spline engagement depth before sliding the yoke onto the transmission.
• Ensure proper phasing with the opposite yoke to avoid vibrations.
• Never force the spline entry; if it doesn’t slide in easily, double-check your alignment.
• Use a torque wrench to secure the yoke to the companion flange according to manufacturer specifications.
• Inspect the mating surfaces for wear or damage before installation.

In summary, the 3503-314 yoke is designed for reliability and performance in demanding applications. Proper installation is key to maximizing the lifespan of your driveline components, so take the time to ensure everything is aligned and torqued correctly.
