JE Pistons 400 SBC DOME 18DEG Set of 8 Pistons

JE Pistons is known for making well-built forged racing pistons, drawing on over 75 years of experience to create parts for domestic engines. This set of 8 pistons is specifically made for a 400 SBC engine with an 18-degree dome configuration and a 4.165-inch bore. These pistons are engineered to give you the best combination of durability and performance for high-demand applications.

These pistons are forged in the USA from 2618 aluminum, which gives them the strong tensile strength needed for serious performance builds. They feature JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on the specific application, they may also include an accumulator groove to help manage combustion gas pressure, improving ring seal for consistent power, and a skirt coating to reduce friction and wear on the cylinder walls while also cutting down on operating noise. Each piston is designed specifically for the 400 SBC engine and its intended use, ensuring optimized performance and durability.

This kit includes 8 pistons, each with a 4.165-inch bore, a 1.125-inch compression distance, and a 0.927-inch pin. Please note that this part is not CARB approved and cannot be shipped to California.
