JE Pistons 400 SBC DOME -12 Set of 8 Pistons

This is a set of eight JE Pistons 400 SBC DOME -12 pistons, designed for a 4.145 inch bore. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is essential for engines built for demanding performance applications. They are specifically made for the 400 SBC engine and are intended for high-demand use, whether that's on the dirt track or the drag strip.

JE Pistons has incorporated several design features to enhance performance and durability. The proprietary Forged Side Relief (FSR) forging design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

This set includes pistons for an 8-cylinder engine, with a 4.145 inch bore, a 1.000 inch compression distance, and a 0.927 inch pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
