2603-25 – Transmission Yokes – 7260 Series – 23/25 X 1.083 Splines – 1.495″ Hub Dia

2603-25 is a Transmission Yoke that plays a crucial role in connecting your driveshaft to the transmission. If you’re experiencing vibrations or a loss of power transfer, this yoke is likely the culprit. Designed for Mazda vehicles and some early Mustangs, it features a 7260 Series design with a spline count of 23/25 X 1.083 inches. This specific spline configuration ensures a secure fit and proper torque transfer, which is essential for maintaining driveline integrity.

When diagnosing driveline issues, look for signs of wear on the yoke splines. If you notice a clunking noise during acceleration or deceleration, it may indicate that the yoke is not engaging properly with the transmission. Additionally, if the yoke is worn, it can lead to excessive play, which can cause further damage to the U-joint and other components.

Key specifications of the 2603-25 include:

• 23/25 X 1.083 Splines
• 7260 Series
• Counter Bore Diameter: 1.179 inches
• Hub Diameter: 1.495 inches
• Center U Joint to End: 6.000 inches

Installing the 2603-25 yoke requires careful attention to spline engagement depth and phasing with the opposite yoke. Never force the spline entry, as this can lead to further damage. With the right fit and specifications, this yoke will restore proper function to your driveline, ensuring smooth operation and reliable performance.
