JE Pistons BMW S52B32US 9:1 KIT Set of 6 High-Performance Forged Pistons

Designed for high-demand performance applications, this set of six pistons enhances the efficiency and durability of your engine. Utilizing advanced manufacturing techniques, these components are crafted from 2618 aluminum, providing exceptional tensile strength to withstand rigorous driving conditions.

The proprietary Forged Side Relief (FSR) design minimizes friction and power loss, featuring a reduced skirt width that not only saves weight but also incorporates a shorter wrist pin for improved performance. Additionally, the skirt coating (dependent on application) is engineered to lower friction and wear on both piston skirts and cylinder walls, contributing to a quieter operation.

An accumulator groove, also dependent on application, effectively reduces pressure from combustion gases, thereby minimizing ring fluttering and enhancing ring seal for consistent power delivery. This kit comes complete with high-quality wrist pins, locks, and premium JE Pro Seal piston rings, ensuring that all components work harmoniously to optimize engine performance.
