MAHLE 3150074-035 Precision-Ground Plasma-Moly Performance Piston Ring Set +0.035 Over

The MAHLE 3150074-035 is a precision-ground performance piston ring set designed for engine rebuilds and performance applications requiring reliable compression sealing and superior oil control. Engineered to OE-quality standards, this set is manufactured to exacting tolerances and is offered in a +0.035" oversize to accommodate bored or worn cylinder applications.

Key Features:

• Plasma-moly top compression ring — provides excellent scuff resistance, faster break-in, and long-term durability under high heat and pressure
• Napier tapered hook groove (THG) second ring — acts as a check valve to relieve combustion pressure buildup beneath the top ring, delivering superior oil control and improved compression sealing
• 3-piece oil control ring assembly — features a stainless steel expander between two chrome-faced steel rails for maximum conformability within the cylinder bore
• Keyed or indexed design — engineered to prevent incorrect installation, reducing assembly errors during engine builds
• High-strength alloy materials — built to withstand increased operating temperatures, higher combustion pressures, and the demands of modern performance engines
• File-fit design — allows the builder to custom-fit ring end gaps for specific applications and power levels
• Sold as a complete set — includes all rings required for one engine
