MAHLE 301-1298 OEM Replacement Engine Piston

The MAHLE 301-1298 is a precision-engineered OEM-replacement engine piston built to meet or exceed original equipment manufacturer specifications. MAHLE is one of the world's foremost suppliers of engine components, trusted by OEM manufacturers and professional engine builders alike for their dimensional accuracy, thermal management, and long-term durability.

Key Features:

• OEM-Grade Aluminum Alloy Construction — Manufactured from high-strength eutectic aluminum alloy, proven in millions of production and high-performance engines worldwide for superior heat resistance and reduced weight
• GRAFAL® Anti-Friction Skirt Coating — MAHLE's proprietary Grafal coating applied to the piston skirt reduces friction, minimizes cylinder bore wear, and suppresses piston noise for a quieter, longer-lasting engine
• Phosphate Dry Lubricant Coating — A factory-applied phosphate coating provides a protective lubricant film in pin bores and ring grooves during initial startup and break-in, guarding against micro-welding and galling
• Compensated Ring Grooves — Precision-machined ring grooves ensure proper ring loading and consistent oil control throughout the service life of the piston
• Expansion-Controlled Design — Engineered for tight piston-to-wall clearances, reducing engine noise, minimizing emissions, improving oil control, and extending overall engine life
• Piston Pin Offset — Pin offset geometry further reduces engine noise and piston slap during cold starts and normal operation
• Crown Markings — Piston diameter, installation clearance, and directional orientation are clearly marked on the crown for accurate, efficient installation

The MAHLE 301-1298 is a direct-fit replacement piston suited for engine rebuild and repair applications. Each piston is manufactured to tight dimensional tolerances, ensuring reliable sealing, reduced blow-by, and consistent combustion performance restore to OEM standards.
