Key Features:

  • Forged construction from high-strength 2618 aluminum alloy for superior durability
  • 4.156-inch bore diameter with 0.030-inch oversized bore
  • D-cup (dished) design with 255cc volume for optimized compression ratios
  • Precision-machined ring grooves for improved sealing and oil control

Icon's forged pistons are manufactured to exacting tolerances and designed to withstand the rigors of high-performance engine builds.
