MAHLE 3010218B Plain Ring Set 4.315in Bore 1/16in PC479 Fire-Power

The MAHLE 3010218B is a high-performance PC479 Fire-Power piston ring set engineered for 4.315-inch bore applications. PC479 compression rings provide superior ring durability, stable radial tension, superior combustion sealing and oil control, while protecting the cylinder walls—netting additional horsepower while extending engine life. This plain ring set features 1/16-inch top compression rings designed to withstand the demands of high-performance and racing engines.

Key Features:

• 4.315-inch bore diameter for big block V8 applications
• 1/16-inch (0.0625-inch) PC479 Fire-Power top compression rings
• Plain ring design for precise file-to-fit installation
• Superior radial tension stability for consistent cylinder sealing
• Advanced ring materials optimized for reduced friction and extended life
• Engineered for high-output engines including nitrous, turbocharged, and supercharged applications

MAHLE's PC479 Fire-Power ring sets are engineered to meet the demands of today's high-performance engines with increased combustion pressures and operating temperatures. The plain ring design allows builders to custom-fit ring gaps to their specific application for optimal performance and sealing. MAHLE Performance piston rings evolved from their pioneering use of piston ring simulation and computer development tools to develop rings that provide "free" horsepower by successfully minimizing friction, with a large selection of coordinated piston ring sets available in a variety of sizes, designs, materials, and coatings.
