The JE Pistons 301942S is a premium forged racing piston engineered for high-performance and competition applications. Built from 2618 aluminum alloy, this dome-top piston is designed to handle the extreme heat and cylinder pressures found in forced-induction, nitrous, and high-compression naturally aspirated race engines.

Key Specifications:

  • Alloy: 2618 forged aluminum
  • Top Style: Dome
  • Bore Diameter: 3.287 inches
  • Compression Distance (CD): 1.165 inches
  • Pin Diameter: 0.787 inches (20.0mm)

Key Features:

  • Forged in-house by JE Pistons using proprietary tooling and processes for superior grain structure and strength
  • 2618 alloy provides exceptional toughness and fatigue resistance, ideal for boosted or nitrous applications where thermal and mechanical loads are extreme
  • Precision CNC-machined to tight tolerances for consistent fit, ring seal, and optimal performance
