The Level 5 CTS-V axles are designed to handle up to 1000HP. Using our chromoly center bars, 108mm Porsche-style CV's and bolt-on chromoly inner and outer stubs, these are a direct bolt-on that fit the stock hubs and come complete with all the necessary hardware. Not only will these axles handle the horsepower, we have used different diameter bars on each side which will eliminate wheelhop! The CTS-V is notorious for wheelhop at launch which can be extremely damaging to the drivetrain and makes getting traction very difficult. By allowing the axle bars to torsionally twist at different rates the result is traction, not wheelhop. These axles are priced as a set and have a 1-year warranty.
