JE Pistons BBC .510 DOME Set of 8 Pistons

When you're building a serious big block Chevy engine, the pistons are a critical component. What you get in this kit is a set of eight JE Pistons, forged from 2618 aluminum. This material is chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard, whether that's on the drag strip or in a high-performance street application. These pistons are made 100% in the USA, with JE Pistons bringing over 75 years of experience to the table.

JE Pistons uses a proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and power loss by reducing the skirt width, and they also save a bit of weight by using a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to reduce ring flutter and improve ring seal for more consistent power delivery. Some applications also include a skirt coating that's designed to cut down on friction and wear on the piston skirts and cylinder walls, which can also help reduce operating noise. These pistons are designed specifically for each engine and use case, aiming for optimized performance and durability.

This particular set is for a 4.600 inch bore with a 1.395 inch compression distance and a 0.990 inch wrist pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance BBC, these pistons are a solid option backed by a lot of experience.
