EVO III 4th Gear -- Discontinued by Mitsubishi, but we have a few of these left in stock!

Will fit into a 1992 style transmission with minimal modifications to the 3-4 hub. This gear will also work in 93-99 transmission, as long as you have a 92 style 3-4 shift rail, shift fork, and 3-4 hub/slider assembly. You will also need the EVO III 3rd.

The 1990 will not work as the 90-early 91 gear sets had the wrong gear helix angle on the Intermediate Shaft and Center Diff.
