JE Pistons Chevrolet Big Block Piston Kit 4.610 in Bore 1.120 in CH 29.50 CC -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 4.610 inch bore and feature a 1.120 inch compression height with a 29.50 cc dome volume. JE Pistons has over 75 years of experience crafting pistons for demanding racing applications, and these are no exception.

Each piston is forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines under heavy load. They incorporate JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also contributes to saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. A skirt coating, if included for your application, further reduces 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 offer optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road or racing use where maximum performance and reliability are paramount.
