3642-251 – Stub & Midship Shaft – 30 X 0.950 Splines – Butt Dia 2.375″ – Tube Dia Wall 2.500X0.065

The 3642-251 Stub & Midship Shaft is engineered for optimal torque transmission in driveline applications. With a spline count of 30 X 0.950, this shaft provides a robust connection between the transmission and differential, ensuring that power is efficiently transferred without slippage. The 2.375″ butt diameter is critical as it determines the compatibility with specific yokes and components, ensuring a secure fit that can handle the demands of high-torque applications.

Measuring 5.450″ from end to weld, this shaft is designed to fit precisely within the required length constraints for various vehicle applications. The splines length of 1.404″ allows for adequate engagement with the mating components, which is essential for maintaining alignment and preventing premature wear. Additionally, the tube diameter wall of 2.500″ with a thickness of 0.065″ contributes to the overall strength and durability of the shaft, allowing it to withstand the stresses encountered during operation.

• Verify spline count and diameter for compatibility.
• Ensure correct length from flange to flange for proper fit.
• Check for runout and balance to avoid vibrations.
• Torque all fasteners to manufacturer specifications.
• Inspect phasing marks during installation to maintain alignment.

In summary, the 3642-251 Stub & Midship Shaft is a vital component for any driveline setup, delivering reliability and performance where it matters most.
