JE Pistons BMW S50B30US 11.5KIT Set of 6 Pistons

If you're rebuilding the heart of your BMW S50B30US engine for serious performance, a set of high-strength pistons is crucial. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of high-performance applications where stock pistons might not hold up. They are designed specifically for the S50B30US engine, ensuring they work correctly with your specific setup.

JE Pistons has been making performance pistons for a long time, and these are made 100% in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, contributing to better durability and potentially improved performance. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, which can improve ring seal and keep power consistent. Some applications also come with a skirt coating to further reduce friction and noise.

This kit includes everything you need to get your engine rebuilt: six pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Keep in mind 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 procedures.
