Have you increased your horsepower? Running a power adder? Done some mods to provide a neck-snapping launch?

Don't over look the weak link in your drivetrain...the driveshaft. Everyone knows the stock rear doesn't hold up to much, the driveshaft won't either. When a driveshaft goes it will take expensive parts with it! Don't gamble with your safety, replace the weak link in your drivetrain with one of our "Extreme-Duty" driveshaft assemblies.

For neck snapping launch performance, stay away from an aluminum driveshaft. While the lighter weight may give you a few more horses, the lack of durability isn't worth the gamble. Our shaft is designed to hold up to very high horsepower abuse, yet remains vibration-free at high speeds, you get the best of both worlds.

We precision electronically balance each unit fully assembled. This allows balancing of the shaft just as it will be spinning in your car.
