Pro-Line E-Revo & Summit Pro-Spline HD driveshafts
New from Pro-Line and made for the Traxxas E-Revo and Summit monster trucks are the Pro-Spline HD centre driveshafts. Made from hardened black oxide coated steel, the Pro-Spline drive shafts have a true 6-sided spline that slides smoothly throughout any chassis flex without having to worry about stripping out like the stock plastic drive shafts. The pins are held in place by fully surrounded steel springs and M3 set screws on both ends to handle extreme performance. They come pre-Assembled and fit both the E-Revo and Summit kits.
