3503-3203 – Transmission Yokes – 1350 Series – 31/32 X 1.378 Splines – 1.886″ Hub Dia

When you’re working with the 3503-3203, you’re dealing with a 1350 Series Transmission Yoke that’s specifically designed for TH400 applications. Before you install, make sure to check the spline count; this yoke features 31/32 X 1.378 splines, which are critical for a proper fit. The hub diameter measures 1.886 inches, and the center U joint to end distance is 7.500 inches, so ensure these dimensions align with your setup.

One common mistake during installation is failing to verify the spline engagement depth. Always ensure that the yoke slides on smoothly without excessive force. A forced fit can lead to premature wear or even failure. Additionally, double-check the phasing with the opposite yoke to avoid vibration issues down the line.

• Check spline count and diameter before installation.
• Verify hub diameter and center U joint to end measurement.
• Ensure proper phasing with the opposite yoke.
• Never force spline entry; it should slide on smoothly.
• Inspect for any signs of wear on mating components.

The 3503-3203 yoke is engineered for durability and reliability, making it an excellent choice for your drivetrain needs. Whether you’re replacing a worn-out part or upgrading for performance, this yoke delivers the fit and function you require.
