FPS Pistons

Probe FPS Forged Pistons are designed for heavy duty (towing, etc) or high performance street car, trucks, marine and some racing application. FPS pistons are far stronger than hypoeutectic or hypereutectic cast pistons. Boost and nitrous oxide are compatible.

  • VMS-75 High Silicon Aluminum
  • Tight piston to wall clearance
  • Reinforce piston skirts (eliminated collapsed piston skirts)
  • Increased valve clearance
  • Reduced piston weight
  • Offset wrist pins
  • Press fit piston pins

Anatomy Of A Better Piston

Anti-Setonation Grooves Reduces detonation by tempering pressure spikes, enhances piston life!
Pressure Equaliztion Channel Enhance ring eal, producing more power and enhancing fuel economy!
Slotted Drain Back Holes Slotted drain back holes prevent oil from collecting in the oil ring groove.
CNC Diamond Pinhole Finish Produces ultra straight pinholes and outstanding microfinish for extended life and durability.
Slotted Pin Oiling Slotted pin oiling enhances wrist pin and pin holes oiling for durability and long life.
CNC Diamond Skirt Finishing Retains oil on the piston skirt providing superior anti scuffing capability! Also reduces piston noise!
Ultra-Tight Running Clearance Increases piston and piston ring life and reduces blowby!
Precision Forged of Aircraft Alloy Aluminum Our forgings are approximately 75% stronger than hypoeutectic or hypereutectic castings!
Fully CNC Machined Domes and valve reliefs are fully CNC machined for consistancy and precise clearance to valves and combustion chambers
