What material are these JE Pistons made from?

These pistons are forged in the USA using 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that helps minimize friction and power loss. It achieves this through reduced skirt width and a shorter wrist pin, which also saves weight.

Are these pistons compatible with all BBC engines?

This set is designed for BBC engines with a 4.530 inch bore. It's important to verify compatibility with your specific engine build and application, as they are engineered for specific uses.

Product Details

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've applied that knowledge to this set of BBC FT HD/BLOWN pistons, designed for high-demand performance applications. These pistons are engineered, forged, and machined 100% in the USA, using 2618 aluminum for the high tensile strength needed when you're pushing an engine hard.

This set features a Flat Top design with a 4.530-inch bore and a -3.0cc dish. They incorporate JE Pistons' proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This kit includes 8 pistons, each designed specifically for the BBC engine and its intended use, aiming for an optimized balance of performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
