Mahle Rings Performance 4.180 x 1.5MM Steel Napier Second Ring Plain Ring Set (48 Qty Bulk Pack)

This is a bulk pack of 48 Mahle OE steel Napier second ring sets, designed for a 4.180 inch bore. These rings are specifically the second ring in a piston ring set, featuring a Napier hook design. This design helps to improve oil control and reduce blow-by, especially in performance applications where engines are pushed harder. Mahle is a well-known name in engine components, and this set offers a solid option for engine rebuilds or performance builds where you need a good quantity of reliable rings.

The steel construction of these Napier second rings means they are built to handle the heat and pressure found in performance engines. The 1.5mm thickness is a common size for many performance applications. Having 48 sets in one pack is ideal for shops or builders who work on multiple engines or need to keep a stock of common parts on hand. While these are performance-oriented, they are still designed to fit right into standard piston ring grooves for the specified bore size.
