EVOIII Gears and Ratios
The EVO III 1st 3rd, 4th and 5th gears are the strongest helical units with the coolest ratios on the market!
OEM 1 st gear has a stock ratio of 3.083
EVO III 1 st gear has a ratio of 2.750 which is 11% taller than stock. Taller than the GVR4 gear, and it’s the strongest 1st gear on the market! We can double synchro the EVO III or OEM gear for you also. Pic below is of EVO III 1 st (left) and OEM 1 st (right).
To take a single synchro 2nd gear and replace it with a double synchro unit is nothing magical. All it is, seriously, is a late 1G AWD double synchro gear you can get from the Mits dealer. They are all the same ratio at 1.864 unless you have a FWD/GS-T. We don’t replace this gear unless it is damaged. We have the cool CNC milling equipment to double synchro your OEM gear already, so why spend the extra money on buying the whole gear?

OEM 3 rd gear has a stock ratio of 1.115
EVO III 3 rd gear has a ratio of 1.160. This gear has one less tooth than the OEM unit and is double synchro! It is also the strongest gear on the market! Pic below of EVO III (left), OEM (center 2), and our super double synchro 3 rd (right).
OEM 4 th gear has a stock ratio of .0833
EVO III 4 th gear has a ratio of .0862. Yes, it also comes with the very cool double synchro!! Pic below of EVO III 4 th (left), OEM (center 2), and our super double synchro 4 th (right).
Depending on the year and if your unit is AWD or FWD, the EVO III 5 th gear is the 10% taller unit. EVO III (left) OEM (right).
Now that you know the ratios, lets see how we can make the super secretive ‘close ratio’ units! Looks like the EVO III 1 st is taller, so that would make the ratio between 1 st and 2 nd real close. EVO III 3 rd, well, that one just happens to be shorter, so wouldn’t you know, your 2 nd to 3 rd with the EVO III is now close as well! EVO III 4 th will get you closer to 3 rd!!! That was easy! EVO III 1 st, 3 rd and 4 th will give you that close ratio trans that is so hard to do.
