We began with the strongest 356T6 aluminum alloy. We thickened the case walls, added additional material to support a stronger full width 307 maindrive bearing and a countershaft sealing soft plug, and we reinfornced and thickened the mounting ears. As a final touch, user-friendly straight threat fill and (magnetic) drain plugs with sealing O-rings were added.

Despite these improvements, we preserved the look of a '60s design so our new case won't look out of place under your classic muscle car.

No flex, no leaks, no broken ears.
