JE Pistons BBC FT HD/BLOWN Set of 8 Pistons

If you're building a high-performance big block Chevrolet engine, especially one that's going to see heavy duty use or forced induction like a blower, you need pistons that can handle the stress. This set of eight forged pistons from JE Pistons is built for exactly that kind of application. JE Pistons has been making forged pistons for over 75 years, and they build these right here in the USA using 2618 aluminum, which gives them the strong tensile strength needed for demanding performance builds.

What sets these pistons apart is their specific design for the application. They feature JE's proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight by allowing for a shorter wrist pin. Depending on the specific engine application, these pistons may also come with 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 to further reduce friction and wear on the piston skirts and cylinder walls, which also helps quiet down the engine's operating noise.

This set is designed for a 4.280 inch bore with a 1.765 inch compression distance and uses a 0.990 inch pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for pistons that are proven on the track and built to last under extreme conditions, this set from JE Pistons is a solid choice.
