MAHLE 41768.020 Premium Piston Ring Set for Ford 7.3L Powerstroke Diesel V8

The MAHLE 41768.020 Premium Piston Ring Set is engineered specifically for 1994-2003 Ford 7.3L Powerstroke diesel engines with a 4.130 inch bore (.020" oversize). This complete set includes rings for all eight cylinders, providing everything needed for a comprehensive engine rebuild or performance upgrade.

Advanced Ring Technology:

• SAE 9254 high alloy steel base material delivers higher tensile and yield strength, extended fatigue resistance, and increased material hardness
• Plasma-moly coating on compression rings provides superior wear resistance and faster break-in
• Pre-lapped design seats immediately, virtually eliminating break-in time
• Optimized ring tension reduces friction while maintaining excellent sealing

Superior Design Features:

• CP-20 oil ring assemblies feature an exclusive 20-degree ear angle for optimal side seal against the cylinder wall
• Barrel-faced compression rings provide more efficient compression and reduced blow-by
• Reverse twist intermediate rings deliver better groove side sealing
• Ring dimensions: 1/8 in., 5/64 in., and 3/16 in. thickness

As one of the world's largest OE piston ring manufacturers, MAHLE produces the most technically advanced piston rings in the industry. These rings are designed to restore compression, reduce oil consumption, and enhance engine power and longevity for direct injection diesel applications.
