Mahle Rings Performance Plasma Steel Top Ring 4.100in x 1.0MM .143in RW HVOF Moly Ring Set

Mahle OE is a well-known name for dependable engine parts, and these performance piston rings carry that reputation. They feature a plasma-sprayed steel top ring, which is a strong choice for engines that see a lot of use. The plasma coating helps the ring hold up better against wear and heat, especially in performance applications. These rings are made for a 4.100 inch bore size and have a 1.0mm top ring groove width with a .143 inch ring depth.

The HVOF (High Velocity Oxygen Fuel) Moly coating on these rings is applied to help with break-in and reduce friction. This means they seat well against the cylinder wall and can help maintain good compression over time. They are a well-built option if you're rebuilding an engine and need reliable piston rings that can handle demanding conditions.
