JE Pistons 400SBC STD FT Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set includes eight flat-top pistons designed for a 4.185-inch bore, featuring a 1.000-inch compression distance and a 0.927-inch pin. JE Pistons brings over 75 years of experience to their forged racing pistons, ensuring they are engineered, forged, and machined entirely in the USA for optimal durability and performance.

The proprietary Forged Side Relief (FSR) design is a notable feature, minimizing friction and power loss through a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure, leading to less ring flutter and an improved ring seal for consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

JE Pistons are designed specifically for each engine and intended use, aiming for optimized performance and durability. This set is a solid option for builders looking for robust internal engine components. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
