Product Details

JE Pistons 255774 is a high-performance forged piston set engineered from 2618 aluminum alloy for extreme racing applications. This 4-piston set features a 3.307-inch bore diameter, 1.205-inch compression distance, and 0.787-inch pin diameter with inverted dome/dish crown design for optimized compression ratios in boosted and nitrous applications.

Key Features:

  • 2618 aluminum alloy construction provides superior tensile strength for high-boost and heavy nitrous use
  • Application-specific forgings ensure uniform crown thickness and weight distribution
  • Contact reduction groove minimizes frictional drag for maximum power
  • Accumulator groove increases top ring stability and sealing performance
  • CNC-machined side relief with lower support band adds skirt strength and durability
  • Honed pin bores with double pressure-fed pin oilers for enhanced lubrication
  • Includes wire locks and JE ProSeal piston rings for complete installation

JE Pistons are sold as precision-matched sets to ensure balanced rotating assembly. Designed specifically for professional competition and extreme performance builds where reliability under extreme cylinder pressures is critical.
