JE Pistons Chevy Small Block 4.030in Bore -3.8cc (Right Side) - Single Piston

JE Pistons has over 75 years of experience making forged racing pistons, and they build this specific piston for Chevy Small Block engines. It's a flat-top design with a 4.030-inch bore and a -3.8cc dish, intended for the right side of the engine. This piston is made from 2618 aluminum, which gives it the high tensile strength needed for demanding performance builds.

This piston is forged and machined 100% in the USA. It features a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by minimizing skirt width. Depending on the application, it may also include a skirt coating to further reduce friction and wear, and an accumulator groove to help improve ring seal for consistent power delivery. These features are all aimed at optimizing performance and durability for your specific engine build.

This is a single piston, and it's important to note that it is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and compatibility with your specific engine build.
