JE Pistons 400 SBC .305 DOME Set of 8 Pistons

When you're rebuilding a high-performance 400 SBC engine, you need pistons that can handle the stress. This set from JE Pistons includes eight forged pistons, each designed to meet the demands of serious engine builds. They're made from 2618 aluminum, a material known for its high tensile strength, which is crucial for engines pushed to their limits.

JE Pistons has been in the game for over 75 years, and they build these pistons right here in the USA. They use a proprietary Forged Side Relief (FSR) design, which means the pistons have a reduced skirt width to cut down on friction and power loss, while also saving weight. Depending on the specific application, you might also find an accumulator groove to help manage combustion pressure and improve ring seal, leading to more consistent power. Some applications also include a skirt coating that further reduces friction and wear on the cylinder walls, making for a quieter and more durable engine.

This kit is specifically engineered for the 400 SBC engine with a 4.165-inch bore and a .305-inch dome volume, contributing to a specific compression ratio. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds where durability and performance are paramount, these JE Pistons offer a well-built solution.
