Forged Aluminum Race
Forged diesel pistons are best suited for dedicated drag and pulling
vehicles. Although the performance forged pistons are stronger, the lack
of protection for the top ring groove in the forging will result in a
limited life cycle for street driven applications. Improved strength and
design flexibility still make the Performance Forged pistsons the ideal
choice for competition-only applications.
