JE Pistons Chevrolet LT4 Gen V 4.070 Bore 0.945 Pin -1.320 CD Inv Dome/Dish Pistons - Set of 8

Forged from 2618 aluminum, these JE Pistons are built for the demands of high-performance Chevrolet LT4 Gen V engines. This material choice is key because it offers the high tensile strength needed to withstand the intense pressures and heat generated in performance applications. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to ensure they meet rigorous standards for durability and performance.

Each piston in this set features a 4.070-inch bore and an inverted dome/dish design, specifically tailored for the LT4 Gen V engine. They incorporate JE Pistons' proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design, along with a shorter wrist pin, also contributes to saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to lower operating noise.

This set includes eight pistons, providing a complete solution for rebuilding or upgrading your LT4 Gen V engine. JE Pistons are proven in various racing environments, from dirt tracks to drag strips, demonstrating their reliability and performance capabilities when it matters most. When you're looking to equip your engine with top-tier forged pistons, this set from JE Pistons is a solid option.
