Looking for a ball to pick up and handle more oil then my hy-road so I selected a Dimension. My stats are speed 15-16.5, Axis point 5 1/2 x 1/2 up, revs 275-325. We slected a 4" pin x 5" marked MB x 3 pin buffer. Weight hole 2" right of thumb hole and about 1/2 Down Near the MB of the ball. What kind of reaction would that be ?
