Mahle Rings Performance 4.160in x 1.5MM .151 RW Plasma-Moly Steel Top Ring Moly Ring Set

If you're rebuilding the engine in your vehicle and need to ensure a solid seal between the piston and cylinder wall, a good set of piston rings is essential. These Mahle OE rings are built for a 4.160-inch bore, a common size for many performance and heavy-duty applications. They feature plasma-moly steel top rings, which are known for their strength and resistance to wear, helping to maintain compression and control oil consumption over time.

The design incorporates a 1.5mm top ring and a moly ring, a popular combination that balances sealing performance with durability. This setup helps the rings seat properly against the cylinder wall, reducing blow-by and contributing to efficient combustion. Mahle has a long-standing reputation for well-built engine components, and this ring set is no exception, offering a reliable option for your engine build.
