JE Pistons Chevrolet LT4 Gen V 4.065 Bore 0.927 Pin -1.295CD Inv Dome/Dish Pistons - Set of 8

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their extensive line of forged pistons for domestic engines. This set is specifically made for Chevrolet LT4 Gen V engines, featuring a 4.065 inch bore and an inverted dome/dish design. These pistons are engineered and forged right here in the USA using 2618 aluminum, which gives them the high tensile strength needed for demanding performance applications.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width, and it also saves weight thanks to a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise. JE Pistons designs each set specifically for the intended engine and use, aiming for the best balance of performance and durability.

This is a complete set of 8 pistons, ready to be installed in your LT4 Gen V engine. They are made 100% in the USA, ensuring a well-built product for your high-performance build.
