Product Details
Mahle is known for making solid OE replacement parts, and this Piston Ring Set is no different. This set is designed for a 4.035 inch bore and features steel Napier rings with dimensions of .043 inch for the top ring and .135 inch for the second ring. These rings are built to help your engine seal properly, keeping combustion pressure where it belongs and oil out of the combustion chamber.
The Napier design on the top ring is a common feature that helps with oil control and ring rotation, contributing to better overall engine performance and longevity. This set is a well-built option for rebuilding or refreshing your engine, ensuring a good seal between the piston and cylinder wall. It's important to note that these rings are not CARB approved and cannot be shipped to California.
