Product Details

JE Pistons 243316 is a high-performance forged piston set engineered from premium 2618 aluminum alloy for demanding racing and high-boost applications. This 8-piston set features a dome crown design with a 4.610-inch bore, 1.120-inch compression distance, and 0.990-inch pin diameter, precision-machined for optimal strength-to-weight ratio and thermal stability.

Advanced Engineering Features:

  • Application-specific forgings ensure optimized, uniform crown thickness for consistent heat distribution
  • Contact reduction groove minimizes frictional drag and improves efficiency
  • Accumulator groove increases top ring stability and sealing for maximum compression
  • CNC-machined side relief with lower support band provides additional skirt strength and wear resistance
  • Honed pin bores for precise pin fit and reduced friction
  • Double pressure-fed pin oilers ensure adequate lubrication under extreme conditions
  • Wire locks included for secure pin retention

Each set includes JE ProSeal piston rings matched to the specific bore and application. All JE Pistons are sold as weight-matched sets to ensure perfect engine balance. Backed by over 60 years of racing piston engineering excellence, these pistons are trusted by engine builders worldwide for Chevy, Ford, Mopar, and Buick performance builds.
