This material offers the high tensile strength needed when you're pushing your Honda B Series engine hard, whether that's on the track or in a serious street build. Each piston features a 4.0cc dome and a specific 82.5mm bore size, designed to optimize performance and durability for your engine. JE Pistons has been a leader in forged racing pistons for over 75 years, and these are engineered, forged, and machined entirely in the USA.

JE Pistons applies its experience to create a piston set that minimizes friction and power loss. The proprietary Forged Side Relief (FSR) design uses a reduced skirt width, and a shorter wrist pin further saves weight. Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure, which improves ring flutter resistance and enhances ring seal for consistent power delivery. A skirt coating, also application-dependent, is used to reduce friction and wear on the piston skirts and cylinder walls, which also helps to lower operating noise. This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for a solid rebuild.

This set is designed specifically for the Honda B Series engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
