JE Pistons BBC FT HD/BLOWN Set of 8 Pistons

JE Pistons is known for making strong, reliable forged racing pistons, and they've put over 75 years of experience into this set for BBC engines. These aren't just generic pistons; they're forged and machined right here in the USA using 2618 aluminum, which gives them the high tensile strength needed for serious performance builds, especially those running heavy duty or blown applications. They're designed specifically for your engine type to give you the best mix of lasting durability and raw power.

You'll find JE's proprietary Forged Side Relief (FSR) design here. This means the pistons have a reduced skirt width and a shorter wrist pin, which helps cut down on friction and power loss while also saving weight. Depending on your specific application, these pistons might also come with an accumulator groove. This feature helps manage combustion gas pressure, reducing ring flutter and ensuring a consistent seal for steady power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also lead to a quieter engine operation.

This set is for an 8-cylinder engine with a 4.560-inch bore. It includes 8 pistons, each with a flat top and a -3.0cc dish. The wrist pin is 0.990 inches, and the compression distance (CD) is 1.245 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
