New from Exotek Racing comes the aluminum Ultra Diff Housing for the Tamiya F104 F1 cars. The one piece F104 Ultra Diff Axle reduces the play and weight of the stock axle with extra machining to reduces weight to just 4 grams (compared to 7 grams stock). The Ultra Diff Housing also features extra machining to reduce the overall weight to 3.6 grams (from 5 grams stock). Both are machined with exacting diff ring tolerances to ensure better diff ring fit so it will no longer slip back and forth like the stocker. The Exotek F104 Ultra Diff Housing and Axle are available in your choice of black or blue anodizing.
