JE Pistons Honda K24 87.5mm Bore -15.9cc Dome 9.25:1 CR Kit - Set of 4 Pistons

If you're rebuilding the engine in your Honda K-series vehicle for serious performance, a set of forged pistons is a critical component. These JE Pistons are built from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of high-performance applications where stock cast pistons might not hold up. They are designed specifically for the K24 engine to optimize both durability and performance, whether you're building a track car or a street machine that sees hard use.

JE Pistons has over 75 years of experience in creating forged pistons, and these are made 100% in the USA. They feature a proprietary Forged Side Relief (FSR) design which helps minimize friction and power loss by reducing skirt width, and also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and prevent fluttering. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This kit includes everything you need to get your K24 engine rebuilt with these strong pistons: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
