What is the purpose of the steel top ring?

The steel top ring is designed to provide a strong seal against the cylinder wall, helping to maintain compression and prevent combustion gases from escaping into the crankcase. Steel offers good durability and wear resistance.

Are these rings suitable for all engine builds?

These rings are specifically designed for a 4.100 inch bore and are intended for performance or heavy-duty engine rebuilding. It's important to match them with the correct pistons and ensure proper cylinder wall preparation for optimal performance.

About this part

Product Details

When you're rebuilding the top end of your engine, getting the right piston rings is crucial for proper sealing and performance. These steel top piston rings from Manley Performance are designed for a 4.100 inch bore, a common size for many performance and heavy-duty applications. They are built to ensure a tight seal between the piston and cylinder wall, which is essential for maintaining compression and preventing blow-by.

Manley Performance is known for making well-built engine components, and these rings are no exception. The steel construction offers good durability and resistance to wear, especially in demanding conditions. The specific ring dimensions, 1.2mm for the top ring and 2.5mm for the second ring, are designed to work with pistons intended for these sizes, helping to optimize combustion chamber sealing. Proper installation is key here; ensure your cylinder walls are honed correctly and the rings are seated properly to get the best results from this set.

This set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
