JE Pistons LS ASYM FT 4.100STRK Set of 8 Pistons

This is a set of eight JE Pistons LS ASYM FT 4.100STRK pistons. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications. They are designed specifically for LS engines to provide an optimized combination of performance and durability.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and reduce ring flutter for more consistent power. Some applications also include a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, while also helping to lower operating noise.

This set includes pistons with a 4.065 inch bore, a 1.065 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.
