Performance Cast Pistons
Designed for street/strip or pulling trucks making 400-1000HP that still get used as a daily driver or work truck. Machined from OE castings (retaining the cast iron ring insert) to give the same drivability and longevity of a replacement piston with additional strength necessary for modified engines.

  • Performance-oriented combustion bowl with design features intended to reduce erosion issues caused by high pressure, long duration and advanced timing.
  • Lower compression ratios (0.5 to 1.5 pts, or custom depending on application) allowing more flexibility for high output tuning.
  • Fully radiused valve pockets, where applicable to reduce drag and increased scuff resistance.
  • Rings, pins and clips included.
