Mahle Rings Perf 4.190in x 1.5MM .151 RW Plasma-Moly Steel Top Ring Moly Ring Set (48 Qty Bulk Pack)

What you get in this pack is a bulk quantity of 48 sets of Mahle OE Piston Rings, specifically designed for a 4.190-inch bore. Each set includes a 1.5mm plasma-moly steel top ring and a moly ring, ready for engine rebuilding. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Getting this seal right is key to an engine's performance and longevity.

Mahle has built a solid reputation for producing well-made engine components, and these rings are no exception. The top ring is made from plasma-moly steel, a strong material known for its durability and resistance to wear, especially under high temperatures. This is paired with a moly ring, which helps with oil control and further reduces friction. The 1.5mm top ring thickness is a common specification for many performance and heavy-duty applications, offering a good balance of sealing ability and piston crown land clearance. This bulk pack is ideal for shops or builders who frequently work on engines requiring this specific bore size.

When you're rebuilding an engine, the piston rings are one of those critical components that you don't want to cut corners on. Ensuring a proper seal is paramount for compression, power, and oil control. This 48-piece bulk pack from Mahle OE gives you the quantity you need for multiple builds or for a large project, all with the assurance of a well-known brand in engine parts.
