Mahle S224-3852-0.50MM Engine Piston

OE-Style Oversize Piston

MAHLE piston S224-3852-0.50MM is an oversize engine piston built for Ford Super Duty diesel applications that need precise cylinder fitment. It uses OE-quality construction with features aimed at ring control, oil control, and reduced operating noise.

Key Features

• Hypereutectic piston material for stable performance under heat.
• Bowl-style piston head for diesel combustion chamber geometry.
• Oversized 0.50 mm service size for rebuild applications.
• Compensated ring grooves help maintain proper ring loading and oil control.
• Expansion-controlled design supports tight fitting clearances.
• Part number S224-3852-0.50MM for accurate ordering and identification.

Detailed Description

This MAHLE piston is engineered as an OE-quality replacement for rebuilds that require an oversize piston with controlled clearances. The hypereutectic construction and bowl head design support consistent combustion characteristics, while the compensated ring grooves and expansion-controlled profile help reduce wear, emissions, and oil consumption concerns. The S224-3852-0.50MM piston is a direct-fit service part for Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, and F-550 Super Duty diesel engine applications listed in the fitment data. This part cross-references Ford BC3Z 6108-C for the same application.

Common Repair Uses

• Restoring cylinder sealing after engine wear or machining.
• Replacing a damaged or scored piston during overhaul.
• Correcting oil control issues tied to worn piston and ring surfaces.
• Addressing compression loss in rebuild service.
• Matching oversize bore specifications during engine machining.

Installation Notes

Verify bore size, ring selection, and piston-to-wall clearance before assembly. Fitment notes specify 0.50 mm size, piston without rings, skirt coated, and standard compression. Use ring #42168.020 where listed in the fitment notes. Confirm the engine application and part number S224-3852-0.50MM before installation.
