JE Pistons SBC FSR TOUR SERS GP Set of 8 Pistons

If you're rebuilding a high-performance Small Block Chevrolet engine, you need pistons that can handle the stress and deliver consistent power. This set of eight JE Pistons is built for just that, using their proprietary Forged Side Relief (FSR) design. This means they've got a reduced skirt width and a shorter wrist pin, which not only cuts down on weight but also helps minimize friction and power loss. That's crucial when you're pushing an engine hard, whether it's on the track or the street.

These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for demanding performance applications. JE Pistons has been in the game for over 75 years, and they engineer these specifically for each engine and use case to get the best balance of durability and performance. Depending on your specific application, you might also get an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for steady power. Some applications also include a skirt coating to further reduce friction and wear, which can also help quiet down the engine.

This set includes eight flat-top pistons, each with a 4.035-inch bore, a 1.550-inch compression distance, and a 0.927-inch pin. Keep in mind these are not CARB approved and cannot be shipped to California. If you're aiming for serious performance from your SBC, these pistons are a solid choice built with American-made quality.
