Manley Piston Ring, RING-4.165 1.5,3mm STL TOP

This is a Manley Performance steel top piston ring set, designed for a 4.165 inch bore. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. If you're rebuilding or modifying an engine where performance is key, getting the right rings is a big part of making sure it runs right and lasts.

Manley builds these rings with a steel top ring, which is known for its strength and resistance to scuffing, especially in high-performance applications. The 1.5mm top ring and 3mm second ring dimensions are common in many performance builds, offering a good balance of sealing and oil control. They are designed to fit right and perform reliably under demanding conditions. When you're putting an engine back together, especially one that's going to see hard use, using well-made components like these Manley rings makes a noticeable difference in the final result.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and break-in procedures.
