JE Pistons LS7 STROKER DOME Set of 8 Pistons

If you're building a high-performance LS7 engine, especially one designed for stroking, you need pistons that can handle the increased demands. This set of eight JE Pistons LS7 Stroker Dome pistons is forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it ideal for engines pushed to their limits. These aren't just generic pistons; they are specifically designed for the LS7 engine and stroker applications, aiming for an optimal balance of durability and performance.

JE Pistons brings over 75 years of experience to the table with these components. They feature a proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed for a 4.128-inch bore with a 1.065-inch compression distance and uses a 0.927-inch pin. The dome design has a volume of 1.20 cc, which is important for achieving your desired compression ratio. It's worth noting that these pistons are not CARB approved and cannot be shipped to California. For builders in other states, these pistons represent a solid choice for a robust LS7 stroker build.
