Pro-Line E-Revo Pro-Spline HD axles

Coming from Pro-Line and made for the E-Revo and Summit are the pre-assembled Pro-Spline HD axles. Designed to fit both in the front and the rear the Pro-Spline HD technology debuted on the Pro-Line Pro-MT kit. The driveshafts are made from hardened black oxide coated steel and they feature a true 6-sided spline that slides smoothly throughout the suspension travel 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.
