JE Pistons 350 SBC ULTRA FT GP Set of 8 Pistons

What you get in this kit is a set of eight JE Pistons ULTRA FT GP pistons, designed for a 350 Small Block Chevy engine. These are flat-top pistons with a 4.030-inch bore, a 1.550-inch compression distance, and a 0.927-inch wrist pin. They are made from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see a lot of stress and demand high performance.

JE Pistons has been in the forged piston game for over 75 years, and they build these right here in the USA. They use a proprietary Forged Side Relief (FSR) design that cuts down on friction and power loss by using a narrower skirt and a shorter wrist pin, which also helps save weight. Depending on the specific application, these pistons might also come with an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also quiet things down a bit and reduce operating noise.

These pistons are engineered specifically for the 350 SBC engine and high-demand performance uses, aiming for the best balance of durability and performance. Keep in mind that these are not CARB approved and cannot be shipped to California. For installation, you'll want to refer to the manufacturer's instructions for proper ring gap, piston-to-wall clearance, and assembly details.
