JE Pistons 4.030 350 SBC FT Set of 8 Pistons

When you're building a high-performance 350 Small Block Chevy, you want components that can handle the stress and deliver consistent power. This set includes eight JE Pistons, each measuring 4.030 inches in bore diameter, designed specifically for your 350 SBC engine. These aren't just any pistons; they are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for demanding performance applications where reliability is key.

JE Pistons brings over 75 years of experience to the table, and these pistons are a testament to that. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which works to reduce combustion gas pressure, preventing ring flutter and improving the seal for steady power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

Every part of this set is manufactured 100% in the USA, ensuring a high level of quality control. The flat-top design and specific dimensions like the 1.550 inch compression distance and 0.927 inch pin diameter are all engineered to work together for optimized performance and durability in your engine build. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
