Description

Accumulator Groove, Pin Fit, Thermal Crown, Lateral Gas Ports, and Skirt Coat. Ultra Series pistons are made 100% in the USA.

Features & benefits

  • JE’s proprietary Aligned Grain Flow forging technology providing next-level tensile strength ideal for the extreme cylinder pressures of power adder engine builds.
  • Designed specifically for Ford Gen 3 Coyote Engines. To provide optimized performance durability
  • Includes high-quality wrist pins, and locks
  • Made 100% in the USA
  • Accumulator Groove: A specialty groove between the top and second ring provides added volume for blow-by gases. This helps reduce pressure between the rings, improving top ring seal and minimizing ring flutter at high cylinder pressures.
  • Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
  • Thermal Crown: Applied to the piston crown, this thermal barrier coating reflects heat back into the combustion chamber to improve exhaust gas velocity and scavenging while reducing heat transfer to help extend piston life.
  • Lateral Gas Ports: This process mills slots into the top of the top ring groove and provides a pathway for combustion pressure to get behind the top ring. Resulting in increased ring seal and is most common in circle track applications.
  • Skirt Coat: Skirt Coat reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise

Information

These pistons utilize our dedicated Forged Side Relief (FSR) forging that was specifically designed to increase strength.
