Pro-Line Pro-Spline HD rear axles
New from Pro-Line come the Pro-Spline HD rear axles for the Pro-2 SC and Slash 2WD with ProTrac kit. The Pro-Spline HD technology debuted on the Pro-Line Pro-MT kit and is designed to handle some serious power. Made from hardened black oxide coated steel, the 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. The drive shafts also fit the Stampede and Electric Rustler kits.
