The MAHLE 224-3729WR-1.00MM is an OE-quality replacement engine piston set provided at a 1.00mm oversize bore specification, complete with piston rings, wrist pins, and clips — everything an engine builder needs for a proper rebuild. MAHLE is one of the world's largest OE piston manufacturers, supplying original equipment to major automakers and delivering that same engineering excellence to the replacement market.

Key Features:

• Compensated Ring Grooves — Precision-machined ring grooves ensure proper ring loading and oil control throughout the piston's service life
• Expansion-Controlled Design — Engineered for tight fitting clearances that reduce engine noise, wear, and emissions while improving oil control
• GRAFAL® Anti-Friction Skirt Coating — MAHLE's proprietary graphite-impregnated resin coating reduces drag, scuffing, friction, and cylinder bore wear for extended engine life
• Ready-to-Install Kit — Each set includes mounted piston rings, wrist pins, and retaining clips for convenient, professional-grade installation
• OE Form, Fit & Function — Precision machined to tight tolerances to match or exceed original equipment specifications
• Lightweight Construction — Optimized design reduces reciprocating mass without sacrificing durability, resulting in reduced bearing loads, smoother engine operation, and improved throttle response
• 1.00mm Oversize Bore — Designed for engines requiring a standard 1.00mm overbore during rebuild

MAHLE's piston development program draws from decades of international engineering expertise and OE manufacturing experience, making these pistons a trusted choice for professional engine rebuilders and performance enthusiasts alike.
