Description
Main shaft failure is a common problem in extreme duty GM TH400, 4L80-E and 4L85-E units.

An advanced torsional design with spline and cross-hole refinements make this the most durable 1″ main shaft available. This shaft withstood extensive track and lab testing with unbroken results in the most extreme applications. Recommended for applications above 1,000HP and proven reliable over 3,500HP.
