About this part

Product Details

Mahle OE steel Napier piston rings are designed for a 4.000 inch bore. These rings feature a 1.5mm top ring thickness and a .151 inch ring groove width, with a plain finish. They are a well-built replacement for your engine's piston rings.

The Napier hook design on the top ring helps to improve oil control and reduce blow-by, which can lead to better engine performance and efficiency. This set is a solid option for engine rebuilds where reliable ring seal is critical. Remember that these rings are not CARB approved and cannot be shipped to California.
