The science behind our product.

When you increase diameter and decrease weight of a shaft, you increase its Critical Speed. The Critical Speed of a rotating shaft is the speed in which it begins to see extreme resonant vibrations and becomes unstable. In terms of a sprint car drive shaft, this is when the drive shaft starts to turn into a vibrating jump rope, which typically leads to pre mature U joint failure. Titanium is extremely forgiving, as its fatigue resistance and high tensile strength makes for the perfect material for a properly designed drive shaft. Our drive shafts have the perfect balance of weight, strength and forgiveness of any drive shaft available, PERIOD.

Designed, Developed, and Manufactured in Pennsylvania, USA.

Our drive shafts are designed to work with all of the leading U joint and rear end manufactures.
