Product Details
When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for sealing and performance. This set from Mahle OE features a steel Napier second ring, which is designed to help scrape oil from the cylinder wall and prevent it from getting into the combustion chamber. The Napier hook shape helps it maintain contact with the cylinder wall even under stress.
These rings are made from steel for durability and feature a .043 inch thickness for the second ring, with a .135 inch width for the plain ring. Mahle OE is a well-known name in engine components, and this set is built to meet the demands of a performance rebuild. Proper installation is key to ensuring these rings perform as intended, helping to maintain compression and reduce oil consumption.
