Roller Pucks helps reduce upwards of 25% of your rotating mass in one convenient shot. This weight reduction is achieved by MIP’s Bi-metal outdrive design that offers the weight savings of aluminum (diff ring disk) coupled with the ultimate wear of steal (outdrives) needed for the MIP Roller Pucks. With the introduction of the new Bi-metal diff they also have transferred the bone design over to that of a CVA. MIP has also upgraded the diff balls to tungsten carbide balls for the ultimate in wear and efficiency.
