8. The M22 Rock Crusher 26-spline input shaft sports a wider gear for greater torque capacity. Just because you've found a 26-spline input shaft does not mean you've found an M22 input shaft, which is made of a stronger alloy. The standard 10-spline input shaft found its way into new Muncie M20 and M21 transmissions from 1971-'74.
Many people know about Muncie transmissions and the famous M22 "rock crusher" transmission that has straighter cut gears that allows you to bang the gears …
This bumbed me out since I had previously read that this was an indication that it was a Saginaw not a Muncie. It does have a 7 bolt side cover. Doe this mean it's still an M22 but just manufactured at the Saginaw assembly plant or it's not an M22 "Rock Crusher Transmission". I am just learning !
Some of the best Muncie builders participate on that page. Muncie RPO Codes . Just three types of Muncie 4-speeds are available based on the RPO (regular production option) code used when a car was ordered: …
The first time I heard the term "rock crusher" was in reference to the transmission in the 1967 L88 Corvette. Due to the low gear angle there is a fair amount of gear noise, really like a medium / heavy duty truck transmission. True enough the M22 did trickle out the door in 1965-67 and was buried in the option lists.
Muncie 4-speeds have varying helix angles in the gearsets. Typically, the M20/M21 gearsets have a first-gear helix angle of 26.4 degrees and an input shaft angle of 39 degrees. The reduction in the angle with the M22 is quite substantial. The M22 first gear has an angle of 14.5 degrees and the input shaft is 24.2 degrees.

M22 Rock Crusher. Jump to Latest Follow ... If the trans needs repair, there are no new gears available for these units, for that matter any Muncie. There was 500 sets of gears made outside the US for the M-22, I have no idea how good they are or the cost. It might be a better idea to find a good M-20 or M-21, or purchase one of the Richmond units.
I've installed them both.And In my opinion the M-22 is way better.The M-21 was close ratio but I've broken quite a few more of those,Than a M-22.The M-21 was good enough for a street driven cars,And racing.But the M-22 was far superior to it.I've only broke a M-22 twice.And I broke a M-21 more than 8 times. M22 is superior, but at the expense ...
