Pro-Line Traxxas E-Revo/Summit Pro-Spline HD Driveshafts are designed to handle some serious power and can be used in the front or rear position. Made from Hardened Black Oxide coated Steel, the Pro-Spline drive shafts feature a 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 power and punishment. To top it all off the E-REVO & SUMMIT Pro-Spline HD Axles are Pre-Assembled to make it easy to install and get back to bashing!

Mine lasted for less than two runs. The pin broke in the universal joint. I'm running 6S with a 1700kv, stock gearing. So yes...kinda fast, but not crazy. The stock shafts lasted for almost a year. I was hoping these were stronger. They are NOT. Who makes indestructible shafts for the Summit? The integy ones also broke...)
