MAHLE 3011027 Performance Piston Ring Set 4.625" Bore 1.0mm Plasma-Moly Steel Top

The MAHLE 3011027 performance piston ring set is engineered for high-performance and racing applications requiring superior strength and durability. This precision-manufactured ring set features a 4.625-inch bore diameter with a low-drag 1.0mm x 1.0mm x 2.0mm configuration designed to minimize friction and maximize power output.

Key Features:

• Plasma-moly coated steel top compression ring for enhanced wear resistance and scuff protection
• SAE 9254 steel construction provides exceptional tensile strength, hardness, and fatigue resistance
• 1.0mm top ring, 1.0mm second ring, 2.0mm oil control ring configuration
• 0.143-inch radial wall (RW) design reduces ring tension for improved conformability
• File-fit design allows precise end gap adjustment for optimal sealing
• Engineered to minimize friction and provide "free" horsepower gains
• Standard tension oil control rings included

MAHLE performance ring sets utilize advanced plasma coating technology to extend ring life, eliminate ring breakage, reduce side wear, and minimize groove pound-out problems. This ring set is ideal for sportsman-class racing, high-performance street builds, and engine rebuilds where maximum power and reliability are essential. Designed for 8-cylinder applications requiring a 4.625-inch bore diameter.
