Product Details

JE Pistons 243323 is a high-performance forged piston set engineered from 2618 aluminum alloy for demanding racing and high-boost applications. This 8-piston set features a dome design with a 4.560-inch bore, 1.270-inch compression distance, and 0.990-inch pin diameter, designed for big-block Chevy and similar performance builds requiring maximum strength and heat resistance.

Key Features:

  • Application-specific forging process ensures optimized, uniform crown thickness for maximum strength and heat dissipation
  • Contact reduction groove minimizes frictional drag and improves efficiency
  • Accumulator groove increases top ring stability and sealing for improved compression
  • CNC-machined side relief with lower support band provides additional skirt strength and reduces weight
  • Precision-honed pin bores with double pressure-fed pin oilers for enhanced lubrication
  • Wire locks included for secure pin retention
  • JE ProSeal piston rings included with each set for complete installation readiness

JE Pistons has manufactured forged racing pistons for over 60 years, establishing itself as the industry leader for Chevy, Ford, Mopar, and Buick performance engines. Each piston set is precisely matched to ensure balanced performance and reliability in high-stress racing environments.
