JE Pistons SBC FSR TOUR SERS GP Set of 8 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into this set of 8 pistons for your Small Block Chevrolet. These aren't just any pistons; they're built with a proprietary Forged Side Relief (FSR) design, which means they have a reduced skirt width to minimize friction and power loss, while also saving weight. They're forged from 2618 aluminum right here in the USA, giving them the strong tensile strength needed for high-demand performance applications.

You'll find that these pistons are designed specifically for each engine and its intended use, aiming for that sweet spot between optimized performance and durability. Depending on your specific application, you might also find features like an accumulator groove, which helps control combustion gas pressure to keep your rings sealing consistently. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation. JE Pistons are proven in racing, so you can be confident they're built to handle whatever you throw at them.

This particular set is for a 4.040 inch bore with a flat top design and includes 0.927 inch pins. Please note that these pistons are not CARB approved and cannot be shipped to California.
