In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the Ford Shelby GT500.

We have invested many hours evaluating and refining each of the Shelby GT500 products on our chassis “dyno”, to ensure that we could develop as much power as possible, as safely as possible. End result is our now available "Dyno Tuned Options".

Our site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always developing new ways to create more horsepower.
