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.

Note: These custom made pistons are built to order using your exact specifications. Please allow time for pistons to be manufactured. Once an order is placed it cannot be cancelled or returned.
