MAHLE 224-3538WR-0.50MM OE Replacement Engine Piston Set with Rings 0.50mm Oversize

The MAHLE 224-3538WR-0.50MM is an OE-quality replacement engine piston set designed for 0.50mm oversize bore applications. As one of the world's largest original equipment piston manufacturers, MAHLE engineered this set to deliver the same precision fit and performance characteristics found in factory-installed components.

This "WR" series set includes pistons with pre-mounted piston rings, piston pin, and retaining clips, providing everything the engine builder needs for a complete, ready-to-install assembly. The 0.50mm oversize designation makes it ideal for engines that have been bored beyond the standard dimension during rebuild.

Key Features:

• Compensated Ring Grooves – Engineered to ensure proper ring loading and consistent oil control throughout the piston's service life
• Expansion-Controlled Design – Tight fitting clearances reduce engine noise, minimize wear, lower emissions, and improve oil control
• Pin Offset Design – Reduces piston slap and engine noise during cold starts and normal operation
• High-Temperature Aluminum Alloy Construction – Cast from heat-resistant aluminum for durability under demanding engine conditions
• Lightweight Design – Reduced reciprocating mass lowers bearing loads, improves throttle response, and contributes to smoother engine operation
• Complete Kit – Includes pistons with mounted piston rings, wrist pin, and retaining clips for installer convenience
• 0.50mm Oversize – Designed for engines bored 0.50mm over standard bore diameter

MAHLE is a globally recognized OE supplier trusted by major automotive manufacturers. This piston set meets or exceeds original equipment specifications, making it a reliable choice for professional engine rebuilders and performance enthusiasts seeking OE-level quality.
