Product Details

The JE Pistons 321249R is a single forged racing piston constructed from 2618 aluminum alloy, featuring an inverted dome/dish crown design for precise combustion chamber volume and compression ratio tuning. With a 3.760-inch bore diameter, a 1.165-inch compression distance (CD), and a 0.866-inch wrist pin diameter, this piston is engineered to exacting tolerances for high-performance and racing applications.

Key Features:

  • 2618 forged aluminum alloy construction — the preferred material for forced induction, nitrous, and high-horsepower builds due to its superior strength and thermal fatigue resistance
  • Inverted dome/dish crown — optimized for compression ratio and combustion efficiency in performance engine builds
  • 3.760-inch bore diameter — precision-machined for a consistent, reliable fit
  • 1.165-inch compression distance (CD) — allows accurate piston deck height configuration
  • 0.866-inch wrist pin diameter — compatible with standard high-performance pin and rod combinations
  • CNC-machined to tight tolerances for consistent weight and dimensional accuracy

JE Pistons has been a trusted name in professional motorsports since 1947, supplying forged pistons to top-level racing programs including NASCAR, IndyCar, and NHRA. Every JE piston undergoes Finite Element Analysis (FEA) to simulate thermal and structural stresses before production, ensuring race-proven durability right out of the box.
