Mahle Rings Performance Plasma Steel Top Ring 3.922in x 1.0MM .143in RW HVOF Moly Ring Set

This set includes the top piston rings you need for your engine rebuild. These rings are made from plasma-sprayed steel, a well-built material chosen for its strength and ability to handle high temperatures. The HVOF Moly coating on the ring face helps reduce friction and wear, which is important for keeping your engine running smoothly and efficiently over time. They are designed to seal tightly against the cylinder wall, helping to maintain compression and prevent blow-by.

When you're rebuilding an engine, getting the piston rings right is key to its performance and longevity. These Mahle rings are a solid option for those looking for improved sealing and a durable component. The 1.0mm top ring and 0.143-inch second land width are specific dimensions that ensure a proper fit in many performance applications. Remember, these rings are not CARB approved and cannot be shipped to California.
