About this part

Product Details

If you're building a high-performance Big Block Chevrolet engine, this single dome piston from JE Pistons is a solid choice. It's designed for a 4.320 inch bore and features a .565 inch dome, intended to work with specific cylinder heads and compression ratio targets. JE Pistons has been making performance pistons for a long time, and this one is forged in the USA from 2618 aluminum, which is known for its strength under high stress.

This piston uses JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and save a little weight by using a narrower skirt and a shorter wrist pin. Some applications also get a skirt coating to cut down on friction and noise, and an accumulator groove to help manage combustion pressure for better ring seal. These features all work together to help your engine make power reliably.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. It's sold individually, so be sure to order the correct number for your engine build.
