JE Pistons LS ASYM FT Set of 8 Pistons

If you're building a high-performance LS engine, a solid set of pistons is crucial. This set from JE Pistons, part number 311966, is designed specifically for LS applications and is forged right here in the USA. They use a 2618 aluminum alloy, which gives them the high tensile strength needed to handle the demands of performance engines, whether you're on the drag strip or just want a more robust street setup.

What sets these pistons apart is JE Pistons' experience. They've incorporated features like their proprietary Forged Side Relief (FSR) design, which uses a narrower skirt and a shorter wrist pin to cut down on friction and weight. Some applications also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power delivery. You might also find a skirt coating, which further reduces friction and wear on the cylinder walls, making for quieter operation and longer life. These aren't just generic pistons; they're engineered for the specific demands of the LS engine.

This set includes eight pistons, each with a 4.070-inch bore, a 1.304-inch compression distance, and a 0.927-inch wrist pin. They are flat-top pistons with a -5.00 cc dish. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any LS engine build where durability and performance are key, this set from JE Pistons is a well-built choice.
