-= CPR - Pistons - Probe Forged Pistons - Factory Replacement Series =-
CPRPARTS.COM, Your High Performance Source!

Probe FPS Forged Pistons are designed for heavy duty and high performance use when the application requires a piston that is stronger than a Cast or Hypereutectic Cast Piston. Compression Ratios mirror factory applications and weights are approximately equivalent to stock, minimizing the need to rebalance. 

Probe FPS Forged Pistons are manufactured at a level of quality, with high end features normally only available on much more expensive pistons.

  • Perfect for heavy duty street, street machine, and most racing applications
  • Reinforced forging eliminates collapsed skirts
  • Clean sheet forging design delivers pistons about 70 grams lighter
  • Increased valve relief depth for high performance camshafts
  • CNC Diamond machined skirts decrease wear and increase power
  • Radial Anti Detonation Grooves (reduce detonation by clipping pressure spikes)
  • Pressure Equalization Channel (enhances ring seal, making more power and increasing fuel economy)
  • Factory ring dimensions
  • Press fit wrist pin
  • Includes piston pins
  • 5/64 5/64 3/16 Rings
  • 1/16 1/16 3/16 Rings * Floating Pin *Light Weight
