Description

Accumulator Groove, Double Pin Oilers, Pin Fit, and Skirt Coat. JE Auto Pistons are engineered, forged and machined 100% in the USA

Features & benefits

  • Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
  • Designed specifically for GM LS7 Engines. 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
  • 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.
  • Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
  • 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.
  • 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.
