MAHLE 41706 Clevite Moly Piston Ring Set for GMC 366 CID Truck Engine

The MAHLE Clevite 41706 is a premium molybdenum-faced piston ring set engineered for the GMC 366 cubic inch (6.0L) large-displacement truck engine. Manufactured by MAHLE, the world's largest piston ring manufacturer, this ring set delivers OE-quality fit, finish, and durability for engine rebuilds and overhauls.

The moly (molybdenum disulfide) face coating on the top compression ring provides superior wear resistance, reduced friction, and excellent break-in characteristics compared to standard chrome or plain iron rings. This coating is especially beneficial in heavy-duty truck applications where high cylinder pressures and elevated operating temperatures are common.

Key Features:

• Moly-faced top compression ring for enhanced wear resistance and faster seating
• High-tensile alloy steel construction engineered to withstand extreme firing pressures
• Pre-lapped rings that seat quickly, virtually eliminating extended break-in periods
• Barrel-faced compression ring contact area for efficient sealing and reduced blowby
• Reverse-twist second ring design for improved groove side sealing
• Three-piece oil control ring assembly with chrome-faced steel rails and a spring-steel expander for precise oil film control
• OE-specification tolerances ensuring proper fit in standard-bore cylinders
• Manufactured to meet or exceed original equipment standards

MAHLE Clevite piston ring sets are the preferred choice of professional engine builders worldwide. Each set is produced under strict quality control standards and backed by MAHLE's manufacturer warranty against defects in materials and workmanship. This ring set is sold as a complete set to service one engine.
