JE Pistons BBC CLOSED CHBR Set of 8 Pistons

If you're rebuilding a high-performance Big Block Chevrolet engine, getting the right pistons is crucial for durability and power. This set of eight closed chamber pistons from JE Pistons is built to handle demanding applications. JE Pistons has been making forged racing pistons for over 75 years, and they engineer and machine these right here in the USA using 2618 aluminum, which gives you the strong tensile strength needed for serious performance builds.

These pistons feature JE's proprietary Forged Side Relief (FSR) design. This means they've got a reduced skirt width to minimize friction and power loss, and a shorter wrist pin to save even more weight. Depending on the specific engine application, you might also find an accumulator groove, which helps control combustion gas pressure to keep your rings sealed tight and delivering consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. Because they're designed specifically for each engine and use, you're getting optimized performance and durability.

This set is for a 4.125 inch bore with a 1.765 inch compression distance and a 0.990 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.
