JE Pistons BBC BLOWN ALKY DM Set of 8 Pistons

If you're building a high-performance big block Chevrolet (BBC) engine, especially one designed for blown alcohol (alky) applications, a solid set of pistons is crucial. This set of eight pistons from JE Pistons is crafted from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for the intense demands of racing engines. These pistons are forged and machined entirely in the USA, reflecting JE Pistons' extensive experience in creating durable and powerful engine components.

JE Pistons incorporates several design features to optimize performance and longevity. The proprietary Forged Side Relief (FSR) forging design helps reduce friction and power loss by using a narrower 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 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. Each piston is designed specifically for its intended engine and use, ensuring you get optimized performance and durability for your build.

This kit includes everything needed for an 8-cylinder engine, with a 4.530 inch bore, a 1.520 inch compression distance, and a 0.990 inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Proposition 65 warning.
