JE Pistons SBC FSR TOUR SERS GP Set of 8 Pistons

JE Pistons is known for making well-built forged racing pistons, drawing on over 75 years of experience. They've put that knowledge into this set of 8 pistons for Small Block Chevrolet engines. These aren't just off-the-shelf parts; they're engineered specifically for racing applications to give you a solid combination of durability and performance, whether you're on the dirt track or the drag strip.

These pistons are forged in the USA from 2618 aluminum, which gives them the strong tensile strength needed for high-demand performance builds. They feature a unique Forged Side Relief (FSR) design that helps cut down on friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Depending on the specific engine application, you might also find an accumulator groove to help control combustion gas pressure, which reduces ring flutter and improves the seal for consistent power. 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.

This set includes 8 flat-top pistons with a 4.040-inch bore, a 1.550-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. If you're building a high-performance Small Block Chevy, these pistons are a solid option backed by a company with a proven track record in racing.
