JE Pistons BBC .370 DOME Set of 8 Pistons

When you're building a high-performance big block Chevrolet engine, the pistons are a critical component that needs to handle serious stress. This set of eight JE Pistons is forged from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for demanding performance applications where durability is paramount. These pistons are designed specifically for your engine and its intended use, aiming for an optimized balance of performance and longevity.

JE Pistons brings over 75 years of experience to these forged pistons, and they are manufactured entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This particular set is designed for a 4.500 inch bore and features a .370 inch dome, with a 0.990 inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking to equip your engine with a well-built set of forged pistons that have a proven track record in racing, this JE Pistons set is a solid option.
