JE Pistons 350 SBC ULTRA FT GP Set of 8 Pistons

Forged in the USA from 2618 aluminum, these JE Pistons ULTRA FT GP pistons are built for high-demand performance applications. They feature a proprietary Forged Side Relief (FSR) design that reduces skirt width and uses a shorter wrist pin, which helps minimize friction and power loss while also saving weight. This set is designed specifically for the 350 Small Block Chevy engine, with a 4.030 inch bore and a flat top design that offers a -1.8cc volume, making them a solid choice for builders looking to maximize their engine's potential.

JE Pistons brings over 75 years of experience to the table, and these pistons reflect that expertise. The FSR design is just one example of how they work to improve durability and performance. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve ring seal for more consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to a quieter engine operation and longer component life.

This set includes eight pistons, each engineered and machined 100% in the USA. They are designed to provide the ultimate combination of durability and performance, whether you're building for the drag strip or other high-performance uses. Please note that this part is not CARB approved and cannot be shipped to California.
