Muncie M20, M21 & M22 4-Speed Transmission Bearing Kits

Are you ready to rebuild your classic Muncie M20, M21 or M22 four-speed transmission? Allstate Gear has the Muncie bearing kits you need for your gearbox. We offer two types of kits, letting you choose between Muncie transmission bearing and seal kits for a quick refresh, or kits with Chevy transmission bearings, seals and synchro rings for a complete rebuild.

When ordering, check the size of the countershaft pin. Depending on the model, it may be 7/8 or 1 inch wide. Due to the popularity of these transmissions in performance builds, the internal components may be different from those used at the factory.
