ATI Output Shafts

4.4 out of 5 stars 5 Customer Reviews

ATI output shafts offer heavy-duty performance for high horsepower. The 300M shafts feature an extended bearing surface and are gundrilled to save weight with no governor or speedometer support. They are available in three lengths for different applications. Big power, lots of weight, giant slicks, and a numerically low rear gear signals the necessity for ATI output shafts--they're must-haves for high performance.
