Product Details

The JE Pistons 105041 is a high-performance forged piston set engineered for serious engine builds. Manufactured from 2618 aluminum alloy, these pistons deliver exceptional strength and durability under extreme heat and cylinder pressures. The set includes 8 pistons with a 4.030-inch bore diameter, 23-degree flat top design, and 1.550-inch compression distance with 0.927-inch pin diameter.

Key Features:

  • Application-specific forgings with optimized, uniform crown thickness for improved heat distribution
  • Contact reduction groove minimizes frictional drag for increased power
  • Accumulator groove enhances top ring stability and sealing performance
  • CNC-machined side relief with lower support band for additional skirt strength
  • Honed pin bores with double pressure-fed pin oilers included
  • Wire locks included with each piston
  • Ultra-lightweight design reduces reciprocating mass

Compatible with 3.480-inch and 3.500-inch stroke crankshafts. Recommended ring set: J10008-4030-5. JE Pistons are precision-matched sets, ensuring consistent weight and balance for smooth operation. Backed by over 60 years of racing piston innovation, JE Pistons remains the choice of professional engine builders and racers worldwide.
