Pro-Line is proud to introduce the pre-assembled Pro-Spline HD Center Drive Shafts for the E-REVO® & SUMMIT®! The Pro-Spline HD Center Drive Shafts pair perfectly with Pro-Line’s Front and Rear 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 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. To top it all off the E-REVO® Pro-Spline HD Center Drive Shafts are Pre-Assembled to get you back to bashing faster than ever!
