Brand New SUPERCASE M22 4-Speed Muncie Rockcrusher Style Transmission

This a BRAND NEW SUPERCASE M22 Muncie Rockcrusher Style Transmission. This is a BEEFY version of the original Rock Crusher transmission. Most all the weak points of an original Muncie have been solved by the Super-Case design. The Supercase has extra casting in all the known weak areas. The mid plate is aircraft grade aluminum. The tail housing has also been beefed up. Each new SuperCase transmission is built from the highest quality available. Includes all the goodies: SuperCase, gear ratio choice, heavy-duty set with a oilite bushed side cover. Ready to install and it's available at a great price.
