The 1253-261 Stub & Midship Shaft is engineered to deliver reliable torque transfer from the transmission to the differential. With its unique configuration of 26 x 1.115 splines and a butt diameter of 2.375″, this shaft is specifically designed for applications requiring precise fitment and performance. It’s crucial to note that this shaft must be used with the 1204-261 component and requires the 858018 nut for proper installation.
One of the standout features of the 1253-261 is its tube diameter of 2.500″ and a wall thickness of 0.065″. This combination not only enhances strength but also ensures that the shaft can handle the stresses of high torque applications without compromising on performance. The splines length of 1.120″ is optimized for a snug fit, which helps in minimizing any potential vibration issues.
When installing the 1253-261, it is essential to:
- Verify spline count and ensure it matches the transmission output.
- Check the runout to avoid vibration during operation.
- Torque all bolts to the manufacturer’s specifications to ensure a secure fit.
- Balance the assembly if any vibrations are detected after installation.
Using a shaft that is not precisely matched to your application can lead to premature wear or catastrophic failure. The 1253-261 is designed for specific applications, and using it correctly will ensure optimal performance and longevity.
