Perfect for factory replacement, heavy duty street, and some racing applications! Suitable for high performance street and all forms of racing! Specifically designed for racing applications!

Probe FPS Forged Pistons are designed for heavy duty and high performance use when the application requires a piston that is substantially stronger than a Cast or Hypereutectic Cast Piston.

Loosely based on the old TRW stock replacement forged piston, the Probe FPS Forged Pistons are manufactured using the same ultra-modern machining techniques as the SRS and PRS piston series.

 Probe SRS Forged Pistons are designed for performance and race applications where a strong, lightweight forged piston is an advantage.

With over 200 part numbers now in stock for popular Chevrolet, Ford, Chrysler, and Honda/Accura applications, these full featured pistons are extremely popular for use in street and most racing combinations.

 Probe PRS Forged Pistons are specifically designed for racing applications. Now for the Chevrolet 350 and Ford 2300, Probe PRS pistons are designed to be the lightest pistons available anywhere. In addition to the ultralight weight Probe PRS forged pistons are designed to radically reduce drag and enhance ring seal to increase power.
