What is the bore size and compression distance for these pistons?

This piston set features a 4.125-inch bore and a 1.175-inch compression distance. The dome volume is 6.5 cc.

Are these pistons suitable for a street-driven car?

While these pistons are built for high-demand performance applications, the skirt coating (if included for your application) can help reduce operating noise and wear, making them a viable option for performance street builds. However, they are not CARB approved and cannot be shipped to California.

What is the benefit of the Forged Side Relief (FSR) design?

The FSR design uses a reduced skirt width and a shorter wrist pin. This combination helps to minimize friction and reduce overall weight, contributing to improved performance and durability in high-demand applications.

Product Details

If you're building a high-performance 302 or 351 Windsor small block Ford, these JE Pistons are a solid choice for your engine. They're designed to handle the demands of serious performance applications, whether you're hitting the drag strip or building a track car. These pistons are forged from 2618 aluminum, which gives them the high tensile strength needed for engines that are pushed hard.

JE Pistons has been making performance parts for a long time, and they build these pistons right here in the USA. They use a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by using a shorter wrist pin and narrower skirt. Depending on the specific application, these pistons might also include an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve the seal for consistent power. Some applications also feature a skirt coating that cuts down on friction and wear, making your engine run quieter and last longer.

This set includes eight pistons, each with a 4.125-inch bore, a 1.175-inch compression distance, and a 0.927-inch pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, these JE Pistons offer a well-built foundation for reliable performance.
