JE, Ford, Small Block Ford, 4.155 in. Bore, 1.280 CD, Flat Top, 8 Cyl. Piston Kit

As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its wide range of premium forged pistons for domestic applications. Engineered, forged and machined 100% in the USA, JE Pistons are designed for each specific engine and racing application to provide the ultimate combination of durability and performance. From dirt track to drag strip, JE Pistons’ performance is proven in victory lane time and time again. Equip your engine with the best in forged pistons.

  • Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
  • Designed specifically for each engine and use application to provide optimized performance durability
  • Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
  • Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
  • Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
  • Made 100% in the USA
