Muncie 4 speed gear set



Muncie 4 speed Transmission parts,Gears,Bearing kits,Synchro rings and more!!!!

The Muncie 4 speed,was first designed in 1963,and lasted until 1974. There are 2 basic ratios,close and wide. The close ratio gear box,gives you a fairly high first gear,with the rest of the gears fairly close together,for less rpm drop on your top end. This gear set should be used with a fairly low set of rear end gears,like 3.73 or lower 3.90 4.11 etc... The wide ratio gear set,has a lower 1st speed gear allowing you to use it with a higher set of rear end gears,such as 3.30,3.42 etc... We sell all of the parts,for the muncie 4 speed M20,M21,and M22,at the best prices available.

 Muncie/T10 4 speed diagram case

 There are some differences between the early 1st design muncie and the later
2nd design muncie, One difference is early and late syncro rings and syncro hubs
you can use either one, but you must use the correct ring with the correct hub.
the picture below shows you where to measure across the hub the early hub measures
1 1/8" across and the late hub is 1" across. now look at the syncro ring picture
look at the top part of the ring on the left side,directly behind the pointed
engaging teeth the ledge of the ring comes out about an 1/8" then it steps down
and comes back another 3/16" or so,this is the late ring,it is used with the
narrower 1" hub. the ring on the right does not have this stepdown and is
used with the wider 1 1/8" hub.  Also i get asked alot how do you tell the
difference between the (M20,M21) and the M22 transmission, you can not really tell
by looking at the case ,the difference is the actual cut of the gears,you can see this
in the picture below, the M20 and M21 have a much greater angle to the teeth of
the gear and also will have a twist in the teeth (helical bend), the M22 gear is a
more straighter cut gear teeth and also thicker and wider gapped teeth very
noticeable in the picture.

 Here are some pictures of the new Muncie supercase
and the new Muncie super tailhousing, The new supercase
is cast thicker then the original, it has thicker mounting ears
they are also boxed in preventing the ears from breaking off
like the original cases did. the case is also 3/16" overall longer
then the original, allowing us to use a wider front input bearing.
The case also comes with the new front bearing, drain and fill
plugs, The case also uses a metal soft plug at the front where
the countershaft ends, preventing any leaking of oil down the road.
The new Super tailhousing is also cast thicker then original and
you will also notice the heavy duty ribbing on the top and bottom
of the tailhousing making the whole unit much stronger.
