MAHLE 224-3935WR-1.00MM Engine Piston Set with Rings 1.00mm Oversize 6.6L Duramax LML LGH

The MAHLE 224-3935WR-1.00MM is an OE-quality engine piston set machined to a 1.00mm oversize bore, designed for use during engine rebuilds requiring cylinder boring beyond standard dimensions. As one of the world's largest OE piston manufacturers, MAHLE produces these pistons to the same exacting standards as original factory components.

Each piston features a coated skirt to minimize friction and scuffing against cylinder walls, extending the service life of the rebuilt engine. Compensated ring grooves ensure proper ring loading and consistent oil control throughout the piston's operating range. MAHLE's expansion-controlled design allows for tight fitting clearances, directly reducing engine noise, wear, and emissions.
