JE Pistons Ultra Series GM LT1 Asymmerical Piston Set of 8 Pistons

This is a set of eight JE Pistons Ultra Series asymmetrical pistons, designed specifically for GM LT1 Gen V engines. You get the pistons themselves, ready to be installed in your build. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that demand top performance and durability.

JE Pistons has incorporated several advanced features into this set. The proprietary Forged Side Relief (FSR) design helps reduce friction and power loss by using a narrower, shorter skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise during operation.

Because these pistons are designed specifically for the LT1 engine and its intended use, they offer an optimized combination of performance and durability. They are made 100% in the USA, reflecting JE Pistons' extensive experience in forged racing pistons. Keep in mind that this set is not CARB approved and cannot be shipped to California.
