What specific engine configuration are these pistons designed for?

These pistons are designed for a 400 SBC (Small Block Chevrolet) engine that uses 18-degree cylinder heads. They feature a dome piston design and a 4.145-inch bore.

What materials are these pistons made from and where are they manufactured?

These pistons are forged in the USA using 2618 aluminum, which provides the high tensile strength needed for demanding performance applications. JE Pistons is known for its extensive experience in forged racing pistons.

Are there any special features that help with performance or durability?

Yes, these pistons incorporate JE Pistons' proprietary Forged Side Relief (FSR) design to minimize friction and power loss. They may also include an accumulator groove for improved ring seal and a skirt coating to reduce friction and wear, depending on the specific application.

Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their wide range of forged pistons for domestic engines. This set is specifically for a 400 SBC with an 18-degree cylinder head configuration, featuring a dome design and a 4.145-inch bore. These pistons are engineered and forged right here in the USA, using 2618 aluminum, which gives them the high tensile strength needed for high-demand performance applications.

What sets these pistons apart is their advanced design features. 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, you might also find an accumulator groove, which helps reduce pressure from combustion gases, preventing ring flutter and improving ring seal for consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise. These pistons are designed specifically for each engine and use application, aiming for optimized performance and durability.

This is a complete set of 8 pistons, ready to be installed in your 400 SBC build. They are designed for a 4.145-inch bore with a 1.000-inch compression distance and use a 0.927-inch pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA, ensuring you're getting a well-built component for your performance engine.
