JE Pistons SBC FSR TOUR SERS GP Set of 8 Pistons

If you're building a high-performance Small Block Chevrolet engine, JE Pistons has you covered with their FSR TOUR SERS GP piston set. These aren't just any pistons; they're forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard. JE Pistons brings over 75 years of experience to the table, ensuring these pistons are designed specifically for the demands of racing and high-performance street use.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This means they have a reduced skirt width and use a shorter wrist pin, which not only saves weight but also helps minimize friction and power loss. Depending on your specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to reduce ring flutter and improve the seal for consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down the engine's operation. Every part of this set is made 100% in the USA, from the forging process to the final machining, ensuring you're getting a well-built component ready for victory lane.

This particular set is designed for a 4.030 inch bore with a flat top piston design and uses a 1.000 inch compression distance and a 0.927 inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
