MAHLE 224-3929-0.50MM Engine Piston Set 0.50mm Oversize

The MAHLE 224-3929-0.50MM is an OE-quality oversize engine piston set engineered to restore factory performance in worn or bored engines. Sized at 0.50mm oversize, this set is precision-machined to exacting tolerances, making it an ideal choice for engine rebuilders requiring a reliable, direct-fit replacement solution.

Key Features:

• Compensated ring grooves ensure proper piston ring loading and long-term oil control
• Expansion-controlled design provides tight fitting clearances that reduce engine noise, minimize wear, lower emissions, and improve oil consumption
• GRAFAL® anti-friction skirt coating (graphite-impregnated resin) reduces friction, scuffing, and cylinder bore wear for extended service life
• Pin offset design further reduces piston slap and engine noise
• Lightweight construction lowers reciprocating mass without sacrificing durability, contributing to smoother engine operation and improved throttle response
• Ready-to-install — piston rings are pre-mounted; wrist pin and retaining clips are included for engine builder convenience
• Piston diameter, installation clearance, and installation direction are marked directly on the piston crown

MAHLE is one of the world's largest OE piston manufacturers, supplying pistons to premium OEM applications including high-output and performance engines. Each piston in this set is built to the same standards as original equipment, delivering confidence in every rebuild.
