JE Pistons 4.020 SBC FT Set of 8 Pistons

This is a set of eight JE Pistons, specifically sized for a 4.020 inch bore on a Small Block Chevy (SBC) engine. These are flat-top pistons, meaning they have a relatively shallow dish or no dish at all, which can help increase compression ratio in certain builds. They are made from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for the stresses of high-performance applications. You'll also get the necessary wrist pins, which are 0.927 inches in diameter, and the pistons feature a 1.250 inch compression distance.

JE Pistons has applied over 75 years of experience to these forged pistons, which are manufactured entirely in the USA. The proprietary Forged Side Relief (FSR) forging design is intended to minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can improve ring flutter and enhance ring seal for more consistent power delivery. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

These pistons are designed specifically for each engine and intended use, aiming for optimized performance and durability. It's important to note that this set is not CARB approved and cannot be shipped to California. If you're building a high-performance Small Block Chevy, these pistons offer a well-built option with features aimed at maximizing power and longevity.
