Wiseco BMW M50B25 84.00 mm Bore 38.20 mm CH -1.50 CC Piston Set

This is a set of six forged pistons from Wiseco, specifically made for the BMW M50B25 engine with an 84.00 mm bore. These pistons are designed for serious racing and heavy-duty builds, offering a significant step up in performance and durability compared to stock components. They feature a compression height of 38.20 mm and are constructed from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions.

Wiseco machines these pistons in the USA, ensuring precision in every detail. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal and overall combustion efficiency. The piston crowns are fully machined for a clean, consistent surface. Additionally, these pistons come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The forced pin oiling feature ensures the wrist pin receives adequate lubrication, critical for high-performance applications.

This set is intended for builders who are pushing their engines hard and need components that can handle severe duty. While these pistons offer advanced features for racing, please note they are not CARB approved and cannot be shipped to California. They are a well-built option for those looking to maximize the performance and reliability of their M50B25 engine.
