JE Pistons Chevrolet LT4 Gen V 4.065 Bore 0.945 Pin -1.320 CD Inv Dome/Dish Pistons - Set of 8

When you're building a high-performance Chevrolet LT4 Gen V engine, especially for demanding applications like racing or serious street performance, the pistons are a critical component. This set of eight pistons from JE Pistons is designed to handle the stress and heat that come with boosted or high-compression builds.

Crafted from 2618 aluminum, these pistons are forged in the USA, giving them the high tensile strength needed for high-demand performance. JE Pistons incorporates their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, improving ring seal and preventing flutter, and a skirt coating to further reduce friction and wear while quieting operation.

This set is specifically made for the LT4 Gen V engine with a 4.065 inch bore and a 0.945 inch pin diameter. The inverted dome/dish design is part of the optimization for this particular engine and its intended use, ensuring you get the best combination of durability and performance. Remember, these pistons are not CARB approved and cannot be shipped to California.
