JE Pistons BBC .675 DOME Set of 8 Pistons

If you're building a high-performance Big Block Chevy (BBC) engine, you need pistons that can handle the stress. This set of eight .675 dome pistons from JE Pistons is forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it ideal for demanding performance applications. These aren't just generic pistons; JE Pistons engineers each set specifically for the intended engine and use, aiming for the best balance of durability and performance. You'll find their pistons proven in various racing environments, from dirt tracks to drag strips.

JE Pistons incorporates several design features to help your engine run strong. The proprietary Forged Side Relief (FSR) design reduces friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to improve ring seal and maintain consistent power. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life. Every step, from forging to machining, is done in the USA.

This particular kit is for an 8-cylinder engine with a 4.310-inch bore, a 1.395-inch compression distance, and a 0.990-inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, refer to the manufacturer's installation instructions for proper ring gap, piston-to-wall clearance, and assembly details.
