JE Pistons 426 HEMI DM 12.5/1 Set of 8 Pistons

If you're building a high-performance 426 HEMI engine, you need pistons that can handle the stress and deliver power reliably. This set of eight pistons from JE Pistons is forged from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for demanding performance applications. These aren't just generic pistons; they're specifically designed for the 426 HEMI engine, aiming for optimized performance and durability.

JE Pistons has been in the game for over 75 years, and they build these pistons 100% in the USA. You'll find features like their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and preventing flutter. Some applications also get a skirt coating to further reduce friction and wear on the cylinder walls, which can also help quiet down the engine operation.

This set is for a 4.255-inch bore with a 1.765-inch compression distance and uses a 1.031-inch pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for serious engine builds where reliability and performance are paramount.
