JE Pistons GM LS 4.080in Bore .015 Oversize -10.5cc Asymmetrical Dish/Inverted Dome - Set of 8

If you're building a high-performance GM LS engine, these JE Pistons are a solid choice for your build. This set includes eight pistons, each with a 4.080-inch bore and a .015-inch oversize dimension, featuring a -10.5cc asymmetrical dish/inverted dome design. They are specifically made for LS engines that demand durability and power, whether you're hitting the drag strip or building a serious street machine.

JE Pistons has been a leader in forged racing pistons for over 75 years, and these are forged and machined entirely in the USA from 2618 aluminum. This material offers the high tensile strength needed for demanding performance applications. The pistons feature JE's proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, they may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and maintaining consistent power, and a skirt coating to further reduce friction and wear while also quieting operation.

This piston set is designed for optimal performance and durability in your LS engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all the necessary supporting components, such as rings and wrist pins, which are typically sold separately for custom engine builds.
