It appears that the world has officially run out of the coveted 3.25 ratio final drive gears so we have decided to manufacturer a run of 3.1 final drives. This gear ratio is slightly taller than the 3.25 which gives our Super Coopers better freeway gearing and to reduce engine noise while cruising on the freeway.

The calculation shown represents the speed you will reach in each gear when the engine comfortably reaches 3k rpm.

Note: The first MPH reading is for 10” wheels and Tires. The Second is for 13” wheels and Tires.This gearing is designed for comfortable daily driving without adversely affecting performance.
