Having worked along with the driveshaft shop guys for a while now, and using their products in our 160 mph+ 1/4mi C6Z, there shafts just don't break!
They recently just released a level 5 axles for the 2010 and up cars, and it couldn't have come any sooner, with all the reports of heads/cam, spray, blower, turbo car breaking the axles ect.
So check it out
"Description:The Level 5 axles for the new Camaro SS 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 chromoly axle bars on each side which will eliminate wheelhop. 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"
Feel free to ask questions and we will do our best to answer them asap.
