2-40-2301 Spline Stub 1.250 X 16 spline, Fits: 2.500 X .065

When you encounter a driveline vibration or a failure in torque transfer, the 2-40-2301 Stub & Midship Shaft is often the solution you need. This component is critical in transmitting torque from the transmission to the differential, and any misalignment or wear can lead to significant performance issues.

The 2-40-2301 features a 1.250×16 spline size and a 2.500″ tube diameter, designed to handle the demands of high-torque applications. With a tube wall thickness of 0.065″ and an end-to-weld length of 7.750″, this shaft maintains structural integrity while ensuring optimal load stability. The 16 X 1.375 splines provide a secure fit, reducing the risk of slippage and enhancing overall driveline performance.

Common symptoms of a failing midship shaft include vibrations at specific speeds or a noticeable decrease in acceleration response. If you notice these signs, it’s crucial to inspect the 2-40-2301 for wear or misalignment. This part not only fits seamlessly into your driveline but also ensures that torque is transmitted efficiently, minimizing the risk of further damage to other components.

• Verify spline count and diameter match your application.
• Check for proper phasing during installation.
• Torque bolts to manufacturer specifications for optimal performance.
• Balance the assembly if vibrations persist.

Using the 2-40-2301 Stub & Midship Shaft will help restore your vehicle’s driveline functionality and reliability.
