JE Pistons Chevrolet Big Block 4.625in. Bore 1.215in. CH 40.00CC Dome Piston Kit - Set of 8

If you're building a high-performance Chevrolet Big Block engine, this set of eight forged pistons from JE Pistons is a solid choice. These pistons are designed for a 4.625 inch bore and feature a 40.00cc dome, intended for serious engine builds where durability and performance are paramount. JE Pistons has been a leader in forged racing pistons for over 75 years, and they engineer and machine these right here in the USA.

Crafted from 2618 aluminum, these pistons offer the high tensile strength needed for demanding applications. They incorporate JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for more consistent power delivery. Some applications also include a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This piston kit is made 100% in the USA and is specifically designed for each engine and use application to provide optimized performance and durability. Please 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 for a high-performance build, this JE Pistons kit is a strong contender.
