Product Details

The JE Pistons 182036 forged piston set delivers race-proven performance for high-horsepower engine builds. Precision-machined from 2618 aluminum alloy, these pistons feature a 23-degree solid dome design that increases compression while maintaining optimal crown thickness for strength and heat dissipation. With a 4.155-inch bore, 1.062-inch compression distance, and 0.927-inch pin diameter, this set is engineered for demanding applications where durability and power output are critical.

Key Features:

  • Application-specific forgings for optimized, uniform crown thickness
  • Contact reduction groove minimizes frictional drag for increased efficiency
  • Accumulator groove increases top ring stability and sealing
  • CNC-machined side relief with lower support band adds skirt strength
  • Honed pin bores with double pressure-fed pin oilers for superior lubrication
  • Wire locks included for secure pin retention
  • Oil rail support included for enhanced ring support
  • 23-degree dome configuration for increased compression ratio

Each JE Pistons set includes 8 matched pistons to ensure consistent weight and dimensional tolerances across all cylinders. Recommended ring set: J10008-4155-5. Backed by over 60 years of racing piston expertise, JE Pistons are trusted by engine builders worldwide for Chevy, Ford, Mopar, and Buick performance applications.
