The 6.0L Powerstroke found in 2003-2007 Fords were a pretty capable 325 Horsepower unit. And factory parts were built around those capabilities. With time, mileage and desire for greater power and performance, the factory Flexplate starts to fail. The factory flex plate was manufactured out of stamped steel, and as your power production grows, becomes prone to tearing and coming apart. Aside that, the ring gear can wear down and break teeth leading to failed starts. When you build a truck for power, upgrade critical parts to
handle the additional grunt. CNC Fabrication's Billet Steel Flex Plate
is a perfect SFI rated upgrade balancing affordability with performance and longevity. CNC powder coats their billet flex plates to withstand the elements so they can provide your truck a long service life.
