About this part

Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, and they bring that experience to their BBC APBA Dome piston set. These pistons are engineered, forged, and machined entirely in the USA, using 2618 aluminum which offers the high tensile strength needed for high-demand performance applications. They are designed specifically for each engine and use application to provide an optimized combination of durability and performance, proven time and again in racing victories.

This set of 8 pistons features a proprietary Forged Side Relief (FSR) forging design. This design 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 pressure from combustion gases, which helps prevent ring flutter and improves ring seal for consistent power. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also lowering operating noise.

This kit is for a 4.625 inch bore with a 1.120 inch compression distance and a 4.625 inch stroke. The pin diameter is 0.990 inches. Please note that this piston set is not CARB approved and cannot be shipped to California.
