m22 rock crusher | Hot Rod Forum
Various gear manufactures make replacement gear sets for M22's that will fit in any case with a 1" countershaft. The replacement gear sets do not have identifying rings on the input shaft to tell the ratio. Again, the only tried and true way to tell if it's an M22 is to pull the side cover and look at the gear angle. Vince

When was the M22 first called "rock crusher"?
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 speed....M21, M22, Rock Crusher? | The H.A.M.B.
TonyMemberfrom Rochester NY. USA. ""You can outfit an M20 or M21 with Rock Crusher type gears, OR actually make a 3 speed O/D out of a 4 speed case. Forth being the overdrive obviously.. Actually the 3rd gear station becomes the OD and the 4th gear station becomes 3rd,so the shift pattern is a little weird,1-2-4-3.
Converting to a M22 Rock Crusher | Team Camaro Tech
Simplified, I'll use 3,500 RPM for the baseline. 3500 x 3.08 / 4.10 = 2629 RPM. Using an M22Z with a 3.08:1 is like having an OD with a 4.10:1 AND you still have the takeoff feel of an M22 and a 4.10:1 combination. The M22Z and the 3.08:1 combination is not the answer for everyone but, it is another option. Reply.

What is a M22 Rock Crusher?
The M20 and M21 have the same cut to the gears, the M22 is a straighter cut resulting in a greater strength. Since the M20 and M21 look the same one way to tell them apart (aside from the grooves on the input shaft) is the tooth count on the cluster gear. There are 7 different input shaft possibilities on a Muncie.
M22-Wide vs M22 "Rock Crusher"
The M-22 gear teeth are cut at a noticeably lower angle (not quite at a straight angle as some people say). This lower angle of the teeth imparts greater strength to the gears, but it also increases the noise caused by the meshing of the gears. This higher level of noise is where the nickname "Rock crusher" originated.

A photo from when the last Muncie M22 "Rock Crusher" 4-speed came off the assembly line.
