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

The FSR design minimizes friction and power loss by reducing the piston skirt width. It also saves additional weight by utilizing a shorter wrist pin, contributing to overall engine performance.

What is the benefit of an accumulator groove and skirt coating?

An accumulator groove can help reduce pressure from combustion gases, which may reduce ring fluttering and improve ring seal for consistent power. A skirt coating, if included, reduces friction and wear on the piston skirts and cylinder walls, while also lowering operating noise.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set includes eight dome-style pistons designed specifically for the 351 SBF engine, featuring a 4.125-inch bore and a 0.927-inch pin diameter. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to offer a combination of durability and performance proven on tracks across the country.

The proprietary Forged Side Relief (FSR) design is a notable feature, minimizing friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, which can reduce ring flutter and improve ring seal for more consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed for optimal performance and durability in racing environments. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for specific details regarding pin fitment and assembly.
