Wiseco BMW S52B32 3.2L 86.50 mm Bore 31.00 mm CH -2.70 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This Professional Series piston set is built for serious racers and builders who demand the best for their BMW S52B32 3.2L engine. These aren't just any pistons; they're designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength for handling the extreme pressures of heavy to severe duty race builds.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and durability. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their robust design, making them a solid choice for pushing your engine's limits.

This set includes six pistons, each with an 86.50 mm bore, a 31.00 mm compression height, and a 22.00 mm pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and pins, which are included with this set.
