Product Details

JE Pistons 361278 Ultra Series forged piston set delivers race-proven performance for sport compact and European engine builds. Precision-machined from 2618 aluminum alloy, these dome-top pistons are engineered for high-boost forced induction and extreme performance applications where strength and heat resistance are critical.

Key Specifications:

  • Bore size: 3.386 inches
  • Compression distance: 1.260 inches
  • Wrist pin diameter: 0.866 inches
  • Material: 2618-T61 forged aluminum alloy
  • Crown design: Dome top for increased compression
  • Set includes: 4 pistons

Advanced Features:

  • Thermal barrier crown coating reduces heat transfer and prevents detonation
  • Lateral gas ports improve ring seal and reduce blow-by
  • Thick-wall wrist pins provide superior strength and rigidity
  • Revolutionary forging technology maximizes tensile strength
  • Premium gas-nitrided carbon steel rings included

The 2618 aluminum alloy construction offers superior strength and durability at elevated temperatures compared to standard 4032 alloy, making these pistons ideal for turbocharged, supercharged, and nitrous applications. Each piston is manufactured to exacting tolerances using JE's advanced forging process to ensure consistent weight and optimal performance.
