MAHLE 3030802 Performance Piston Ring Set Bore - 4.165 1.0mm 1.0mm 2.0mm

The MAHLE 3030802 is a high-performance piston ring set engineered for 4.165-inch bore applications. This three-ring assembly features MAHLE's advanced low-drag design with 1.0mm top and second compression rings paired with a 2.0mm three-piece oil control ring assembly.

Ring Configuration:

• Top Ring: 1.0mm steel construction with HV385 supersonic thermal spray coating for superior bonding, scuff resistance, and durability
• Second Ring: 1.0mm steel with phosphate coating for improved sealing and wear resistance
• Oil Ring: 2.0mm three-piece assembly with chrome-plated stainless steel rails and standard tension expander (.113" radial width)

Performance Features:

• File-fit design allows precise end gap adjustment for your specific application
• Low-drag 1.0mm compression ring package reduces friction for measurable horsepower gains
• Ultra-flat ring flanks maximize ring-to-piston groove sealing
• Standard tension oil control provides reliable oil management for street and performance applications
• Chrome-faced oil ring rails deliver exceptional wear resistance and cylinder sealing

MAHLE Performance rings are developed using advanced piston ring simulation and computer modeling to minimize friction while maximizing sealing efficiency. Each ring set is manufactured to exacting tolerances and designed to exceed the demands of high-performance engines. Suitable for V8 applications requiring precision ring control and proven durability.
