Product Details

JE Pistons 243324 is a high-performance forged piston set engineered from 2618 aluminum alloy for demanding racing applications. This 8-piece matched set features dome-style pistons with a 4.600-inch bore diameter, 1.270-inch compression distance, and 0.990-inch wrist pin diameter. Designed for big block and high-output V8 builds, these pistons deliver the strength and durability required for extreme cylinder pressures and sustained high-RPM operation.

Key Features:

  • Application-specific forgings optimized for uniform crown thickness and weight distribution
  • Contact reduction groove minimizes frictional drag for improved power output
  • Accumulator groove enhances top ring stability and sealing under boost or high compression
  • CNC-machined side relief with reinforced lower support band for increased skirt strength
  • Precision-honed pin bores with double pressure-fed pin oilers for superior lubrication
  • Wire locks included for secure wrist pin retention
  • JE ProSeal piston rings included with complete set

Each JE Pistons set is weight-matched to within strict tolerances, ensuring balanced rotating assembly and smooth engine operation. The 2618 aluminum alloy construction provides exceptional tensile strength and thermal fatigue resistance, making these pistons ideal for turbocharged, supercharged, and nitrous oxide applications where durability is critical.
