JE Pistons BMW S50B30US 9:1 KIT Set of 6 Pistons

This JE Pistons kit gives you a complete set of six forged pistons specifically made for the BMW S50B30US engine. You'll get the pistons themselves, along with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have everything needed to rebuild your engine's bottom end with a significant upgrade.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushed hard in performance applications. JE Pistons uses a proprietary Forged Side Relief (FSR) design that helps minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, which can reduce ring flutter and improve the seal for more consistent power. Some applications also include a skirt coating that further reduces friction and wear on the cylinder walls, helping to quiet down operation and extend the life of your components.

This kit is designed to provide optimized performance and durability for your S50B30US engine. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
