Mahle Rings Perf Gas Nitride Steel 4.010 x .043 .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

Starting with a 4.010 inch bore size and a .043 inch thickness, these Mahle piston rings are built for performance gas engines. The steel construction is treated with a nitride finish, a process that hardens the surface and improves wear resistance, which is crucial for maintaining a good seal under demanding conditions. This bulk pack contains 48 sets, making it a solid choice for engine builders or shops working on multiple projects.

Mahle is a well-known name in engine components, and these rings are designed to help your engine perform as it should. The nitride treatment not only helps the rings stand up to heat and friction but also aids in creating a solid seal against the cylinder wall. This helps prevent combustion gases from escaping past the piston and oil from entering the combustion chamber, both of which are key to efficient engine operation and longevity. They are intended for use in performance gas applications where a reliable seal is paramount.

When rebuilding an engine, the piston rings are a critical component that directly impacts compression, oil control, and overall engine health. This bulk pack of Mahle rings offers a way to stock up on a reliable part for future builds. Remember that these rings are not CARB approved and cannot be shipped to California.
