Product Details

The JE Pistons 243321 is a high-performance forged piston set designed for serious racing applications. Crafted from 2618 aluminum alloy for superior strength and durability under extreme conditions, this 8-piston set features an 18-degree dome design optimized for Big Chief, Duke, and Victor cylinder heads. With a 4.600-inch bore diameter, 1.120 compression distance, and 0.990-inch pin diameter, these pistons are engineered for nitrous oxide applications where reliability is critical.

Key Features:

  • Application-specific forgings for optimized, uniform crown thickness
  • Contact reduction groove to minimize frictional drag and improve efficiency
  • Accumulator groove for increased top ring stability and sealing
  • CNC-machined side relief with lower support band for additional skirt strength
  • Integrated oil rail support for enhanced ring pack stability
  • Honed pin bores with double pressure-fed pin oilers for improved lubrication
  • Wire locks included for secure wrist pin retention

JE Pistons are sold as matched, weight-balanced sets to ensure smooth operation and reduced vibration. Recommended ring set: J711L8-4600-5. Backed by over 60 years of racing piston manufacturing expertise, JE Pistons delivers the precision and performance demanded by professional engine builders and racers.
