This is a replacement MIP Female Ball Differential Outdrive for the Associated SC10, and is intended for use with the MIP SC10 Ball Differential Kit. All racers know the advantage of a fresh drive train, so MIP has created a line of stock replacement outdrives. The MIP outdrives are made of alloy steel and are then case hardened. MIP even went a step further and improved on the standard parts with added specs for a tighter fit and reduced weight. Once again MIP has the solution for reduced maintenance cost with added performance.
