Mahle Rings 4.030in Bore .043in 3/16in Plasma Moly Duct Low Tension Reduced Radial Moly Ring Set

Mahle is well-known for making solid OE replacement parts, and this piston ring set is no exception. If you're rebuilding an engine and need a reliable set of rings for a 4.030-inch bore, these are a great option. They're designed to fit right and perform as expected in your engine.

This set uses plasma moly ductile iron top rings, which are known for their strength and resistance to wear. The low tension design helps reduce drag, potentially improving efficiency, while the reduced radial tension means they seat well against the cylinder wall. This combination helps ensure a good seal for optimal compression and oil control.

When you're putting an engine back together, getting the piston rings right is crucial for its long-term health. This Mahle set offers a well-built solution for your rebuild project.
