JE Pistons SBC FSR TOUR SERS GP Set of 8 Pistons

If you're building a high-performance Small Block Chevrolet engine, a solid set of pistons is crucial. This JE Pistons SBC FSR TOUR SERS GP Piston Set is designed to handle the demands of serious performance applications, whether you're hitting the drag strip or the dirt track. JE Pistons brings over 75 years of experience to the table, crafting these pistons entirely in the USA from 2618 aluminum, a material known for its high tensile strength, making it ideal for engines pushing the limits.

What sets these pistons apart is JE's proprietary Forged Side Relief (FSR) design. This unique forging minimizes friction and power loss by reducing skirt width, and it further saves weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to reduce ring flutter and improve ring seal for consistent power delivery. Some applications also include a skirt coating that not only reduces friction and wear on the piston skirts and cylinder walls but also helps quiet down operating noise. These pistons are specifically engineered for the Small Block Chevrolet engine, ensuring optimized performance and durability tailored to its characteristics.

This set includes eight pistons, each with a 4.040-inch bore, a flat top design, a 1.250-inch compression distance, and a 0.927-inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that prioritizes durability and performance, this set of JE Pistons is a well-built choice.
