JE Pistons LS ASYM DISH/INV DM Set of 8 Pistons

If you're building a high-performance LS engine, you need pistons that can handle the stress. This set from JE Pistons, part number 312049, is designed specifically for LS applications and is forged right here in the USA. JE Pistons has been making performance pistons for over 75 years, and they put that experience into every set they produce, aiming for the best balance of durability and performance.

These pistons are made from 2618 aluminum, a strong material well-suited for the high demands of performance engines. They feature JE's proprietary Forged Side Relief (FSR) design, which uses a narrower skirt and a shorter wrist pin to cut down on friction and weight. Depending on the specific application, you might also find an accumulator groove to help maintain a good ring seal and a skirt coating to reduce friction, wear, and noise. These are not just generic pistons; they're engineered for specific engines and uses to give you optimized performance and lasting durability.

This set includes eight pistons, each with a 4.135-inch bore, a 1.115-inch compression distance, and a 0.927-inch wrist pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any high-performance LS build, these JE Pistons offer a solid foundation.
