Every Power Slot rotor starts off as a premium quality blank casting sourced from the best foundries in North America, Europe and Japan. We make sure our products meet and exceed the features of the O.E. (original equipment) rotor, paying special attention to:

• Casting grade and metallurgy per SAE J431.
• Brinnel hardness (BHN) and surface finish (RA.)
• Critical design elements such as the number of cooling vanes, vane direction, heat dams, and plate thickness.

Some competitors will sacrifice quality by using inexpensive off-shore castings made in China or other emerging countries-of-origin. While these economy rotors might be okay for light-duty city driving, they won’t hold up under the rigors of high performance, fleet or severe duty driving.
