JE Pistons LS7 DOME Set of 8 Pistons

Forged in the USA from 2618 aluminum, these JE Pistons are built for high-demand performance applications like your LS7 engine. This set includes eight dome-style pistons, each designed with a 4.125-inch bore and a 0.927-inch pin. JE Pistons brings over 75 years of experience to the table, focusing on creating pistons that offer a strong combination of durability and performance for racing and high-output street use.

The proprietary Forged Side Relief (FSR) design is a notable feature, helping to minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also contributes to saving weight. 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. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down operating noise.

Because these pistons are designed specifically for each engine and use application, you can expect optimized performance and durability. This set is made 100% in the USA, ensuring a high level of manufacturing control. Please note that this part is not CARB approved and cannot be shipped to California.
