Pro-Line is proud to introduce the pre-assembled Pro-Spline HD Axles for the front of the Traxxas Slash 4×4, Stampede 4×4 and Rally! 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 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 Front Pro-Spline HD Axles feature an improved front outer pivot point, which has been moved to be in-line with the steering axis (king pin). This eliminates the forward and backward motion of the stock drive shafts when turning the wheels and results in more consistent power delivery during cornering.
The pins are held in place by zinc coated snap rings and M3 set screws on both ends (PRO Tip: Rotate snap ring so slit is away from the pin and put a drop of Tire Glue on the slit in the snap ring to prevent it from rotating. It is still removable with a flat-head screw driver). To top it all off the Front Pro-Spline HD Axles are Pre-Assembled to get you back to bashing faster than ever!
