This is the ultimate off-the-shelf competition crank for your Mini! First we take a brand new 1275cc A+ Mini crank and we resize the rod journals to the Cooper S spec (1.625"). We then have the cranks wedged, lightened, plasma ion nitrided, balanced and polished. A must for race cars and hot street machines! Also avaialable in a standard 1.75" rod journal size, part no. C-CAM6232.
