Mahle Moly Piston Ring Set for 2008-2010 Ford F-250/F-350/F-450/F-550 (6.4L)

Fits select 2008-2010 Ford F-250, F-350, F-450, and F-550 Super Duty (6.4L).

When rebuilding a high-output direct-injection diesel engine like the 6.4L Powerstroke, ring quality is critical for maintaining compression and controlling oil consumption. This Mahle Moly Piston Ring Set is engineered to meet or exceed original equipment requirements, providing a precise fit within the cylinder bore for a reliable seal and long-term durability.

Mahle utilizes advanced materials and specialized coatings to reduce friction and ring mass. These moly-faced rings are designed to withstand the high thermal loads and cylinder pressures inherent in turbo diesel applications while minimizing wear on the cylinder walls. By reducing friction and optimizing oil control, these rings help restore factory-level performance and efficiency to your Ford Super Duty.

• Direct replacement for 6.4L Direct Injection Turbo Diesel engines
• Moly-coated face reduces friction and improves wear resistance for a longer service life
• Reduced ring mass minimizes inertia to maintain a stable seal across the RPM range
• Engineered to minimize engine oil consumption and satisfy OE requirements
• Manufactured to strict tolerances for consistent fitment and sealing performance
