JE Pistons Chevrolet Small Block 4.155in Bore 1.335in CH 14.50CC Dome Piston Kit (Set of 8)

JE Pistons has been a leader in forged racing pistons for over 75 years, and they bring that experience to their domestic engine components. This set of eight pistons is built for Chevrolet Small Block engines, specifically designed to handle the demands of high-performance applications. They are forged and machined entirely in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushing the limits.

These pistons feature JE Pistons' proprietary Forged Side Relief (FSR) design. This advanced forging minimizes friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life.

This kit is designed for a 4.155-inch bore and features a 14.50cc dome volume. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and durability in your high-demand engine build, these JE Pistons offer a well-built solution.
