These half shafts have been designed for the extreme horsepower and torque the Viper V10 is capable of and then some. They are direct bolt-on axles that are rated up to 1200WHP and are about the most stout axles you can purchase for your 2003-10 Viper. These axles also use a Porsche-style 108mm CV, a significantly larger 30 spline on the chromoly center bar (up from the stock 28 spline bar) the material in the CV cage has also been changed and races to withstand 50% more pressure than a stock 108mm CV. But the Pro-Level axles feature larger billet chromoly 33 spline bolt-on outer stubs and custom wheel hubs to accomodate the larger outer stub spline. Inner flanges are also made from billet chromoly and come with grade 12.9 hardware to complete the package. The axles will have a female flange to accept the factory stubs.
