JE Pistons 400-18 SBC FLAT TOP Set of 8 Pistons

If you're rebuilding a Small Block Chevy (SBC) engine for serious performance, a solid set of pistons is where it all starts. This JE Pistons 400-18 SBC FLAT TOP set is built for those who push their engines hard, whether on the track or the street. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the high tensile strength needed for demanding applications where stock parts just won't cut it.

JE Pistons brings over 75 years of experience to the table, and it shows in the details. You'll find their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width. This design, along with a shorter wrist pin, also helps save weight. Depending on the specific application, these pistons might also include an accumulator groove to manage combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also quiet down engine noise.

This set is designed specifically for the SBC engine and includes eight flat-top pistons, each with a 4.165-inch bore. They are engineered to provide an optimized combination of durability and performance, making them a popular choice for engine builders looking for proven results. Remember, these pistons are not CARB approved and cannot be shipped to California.
