Clevite Plasma-Moly Piston Ring Set Bore Standard

The Clevite Plasma-Moly piston ring set is a performance and OE-replacement engine piston ring set for engine rebuilds and performance builds. Clevite is the MAHLE-owned engine parts brand, and the rings are built around a plasma-moly coated steel top ring.

Key Features:

• Plasma-moly faced top ring: MAHLE Original SAE 9254 steel is combined with a proprietary plasma face coating to extend life, reduce side wear and help prevent ring breakage and groove pound-out.
• Strength and durability: The plasma-moly steel top rings are designed for high tensile strength, hardness and fatigue resistance.
• Multi-piece construction: Sets use separate upper compression, lower compression and oil control rings, with materials and facings (such as chrome-faced oil rings) matched to each application.
• Application-specific designs: Ring widths, tension and material are matched to the engine. Both gas and diesel applications are covered across the line.
• Bore size options: Available in standard and oversize bore options. Select the size that matches your engine's cylinder bore.

Clevite Plasma-Moly rings suit rebuilders and performance builders who want reliable ring seal, long service life and consistent quality from a well-known name in engine bearings and rings. Proper cylinder preparation and ring end-gap checking are recommended during installation.
