997 Ratioset 3+4 Wide 18-31 i=1.722
This Porsche 997 CUP 3rd and 4th gear set has a ratio of 1.722. To accomplish even a longer lifetime of the gears, KMP has designed an unique wide conversion for the 2nd, 3rd and 4th gears. These gears are 7mm wider than the original gears to improve strength and reliability. The gear set can be mounted without any additional changes to the gear casing.
These gears need to be installed in combination with a ‘Wide gear conversion 3/4 kit’. These bushings and spacers are needed to align the wider gears correctly.
Input gear: 18
Output gear: 31
