Product Details
When you're rebuilding the top end of your engine, getting the piston rings right is crucial for sealing and performance. This Mahle OE steel Napier 2nd ring set is designed to help ensure a solid seal between your piston and cylinder wall. The Napier hook design on the second ring helps to scrape oil and maintain a good seal, even under demanding conditions.

The steel construction offers good durability, and the specific dimensions – 3.5236 inches in bore size, with a 1.2mm top groove width and a 0.135-inch ring height – are important for proper fitment within the piston groove.
