MAHLE 224-3730WR-0.75MM Engine Piston Set with Rings Pin Clips

The MAHLE 224-3730WR-0.75MM is a complete engine piston set engineered to original equipment (OE) standards. MAHLE is one of the largest OE piston manufacturers in the world, supplying major automakers globally, and this piston set reflects that same level of precision and quality.

These pistons feature compensated ring grooves that ensure proper ring loading and oil control throughout the life of the engine. The expansion-controlled design allows for tight fitting clearances, which directly reduces engine noise, minimizes wear, lowers emissions, and improves overall oil control.

Key Features:

• OE quality construction meeting or exceeding original manufacturer specifications
• Compensated ring grooves for consistent ring loading and superior oil control
• Expansion-controlled piston design for reduced fitting clearances
• Reduces engine noise, wear, and emissions
• 0.75MM oversized bore for use in engines requiring light reconditioning
• Ready-to-install configuration — piston rings, wrist pin, and retaining clips included
• Engineered by one of the world's largest OE piston manufacturers

The WR designation indicates this set comes complete with rings, wrist pin, and clips, providing everything the engine builder needs for a straightforward, efficient installation. The 0.75MM oversize specification makes this set ideal for engines that have been bored to restore proper cylinder wall integrity.
