The strongest 356T6 aluminum alloy. It has thickened case walls, added additional material to support a stronger full width 307 main drive bearing and a countershaft sealing soft plug, and we reinforced and thickened the mounting ears. As a final touch, user-friendly straight thread fill and (magnetic) drain plugs with sealing O-rings were added.
 

No flex, no leaks, no broken ears.

If you've been looking, you know that good extensions for thirty-year old Muncies are hard to come by. A backbone rib was added. The reverse shift tower was stiffened, and enlarged the oilseal shroud.

Every time you shift your Muncie 's heavy main shaft assembly is thrown back and forth, restrained only by two snap rings and your mid plate. Think of it as a slide hammer and it'll be no surprise that many aluminum mid plates are distorted at the snap ring groove. Our mid plate is made from shock resistant iron.
