JE Pistons BMW S52B32US 11.5KIT - Single Piston

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications in your BMW S52B32US engine. This material choice gives them the high tensile strength needed to handle the stresses of serious engine work, whether you're building for the track or just want a more robust street setup.

JE Pistons applies its 75 years of experience to design these pistons specifically for the S52B32US engine. They feature an inverted dome/dish design to achieve an 11.5:1 compression ratio, and the 3.425-inch bore ensures a precise fit. The Forged Side Relief (FSR) design helps minimize friction and power loss by reducing skirt width, while the included high-quality wrist pins, locks, and JE Pro Seal premium piston rings help ensure a solid seal and consistent power delivery. Some applications may also feature skirt coatings to further reduce friction and noise, and accumulator grooves to improve ring seal.

This kit includes a single piston, along with the necessary wrist pins and locks. Remember 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.
