Available for the Slash 4×4, Stampede 4×4 and Rally, Slash 2wd, Stampede 2wd and 2wd Electric Rustler, Pro-Spline HD Axles made from hardened black oxide coated steel. The Pro-Spline drive shafts have 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 zinc coated snap rings and M3 set screws on both ends.
