The 2nd Generation 5th Bearing Kit is designed for new Corvair engine builds.  This unit requires you have a serviced Corvair GM crankshaft or one of our billet crankshafts.

The 5th Bearing Hub is a single piece 5th bearing Journal/Crank Gear for new engine builds. This unit will be pressed on as part of our Crankshaft Service or our New Billet Crankshaft. Then ground as a unit with the crankshaft. This ensures the hub is concentric with the crankshaft and eliminates the need for adjusting the run out during installation.
