1340-21 – Stub & Midship Shaft – 20 X 1.310 Splines – Butt Dia 2.435″ – Tube Dia Wall 2.560×0.065

The 1340-21 Stub & Midship Shaft is engineered specifically for TOYOTA vehicles, ensuring efficient torque transfer from the transmission to the differential. This component features 20 X 1.310 splines, which are crucial for maintaining a secure connection and handling the torque demands of TOYOTA’s driveline systems. The robust design includes a butt diameter of 2.435 inches and a tube wall thickness of 0.065 inches, providing the necessary strength and stability.

When installing the 1340-21, it’s essential to pay attention to the spline count and dimensions, as mismatches can lead to failure or excessive wear. The splines length of 1.880 inches and an end-to-weld measurement of 6.375 inches are tailored to fit specific TOYOTA models, ensuring proper alignment and phasing. This is critical to avoid vibrations that can affect driveline performance.

• Verify the spline count and dimensions match your application.
• Ensure proper phasing during installation to prevent vibrations.
• Torque all fasteners to the manufacturer’s specifications.
• Inspect the mating components for wear to ensure a complete system check.
• Balance the shaft if any vibrations are detected post-installation.

With the 1340-21 Stub & Midship Shaft, you’re investing in a component that not only fits TOYOTA vehicles but also enhances overall driveline performance. The engineering behind this shaft ensures it can handle the torque paths and load stability required in demanding driving conditions.
