JE Pistons 454 BBC .350 DOME Set of 8 Pistons

Forged in the USA using 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for the 454 Big Block Chevrolet engine, featuring a .350 dome and a 4.560-inch bore. The 2618 aluminum alloy provides the high tensile strength needed to withstand the rigors of performance builds.

JE Pistons incorporates several advanced design features to optimize durability and performance. The proprietary Forged Side Relief (FSR) forging design reduces skirt width, which minimizes friction and power loss while also saving weight. Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes eight pistons, each designed for a 4.560-inch bore with a 1.270-inch compression distance and a 0.990-inch wrist pin. These pistons are engineered and machined 100% in the USA, reflecting JE Pistons' extensive experience in forged racing pistons.
