Manley Piston Ring, RING-4.060/4.065 1.5,3mm GAPLESS TOP

Manley Performance is well-known for making strong internal engine components, and these gapless top piston rings are a prime example of their commitment to performance. If you're rebuilding a high-performance engine where maximum cylinder sealing is critical, these rings are designed to help you achieve that goal. They are specifically made for a 4.060 to 4.065 inch bore size, fitting a wide range of performance applications.

What sets these rings apart is the gapless top ring design. Unlike conventional rings that have a gap, this design features a solid, one-piece construction for the top ring. This eliminates the gap where combustion gasses can escape, leading to improved cylinder pressure and more efficient combustion. This means you can expect a more responsive engine and potentially better power output. The ring set includes a 1.5mm top ring and a 3.0mm second ring, a common configuration for many performance builds. The material and precise manufacturing ensure they can handle the demands of performance engines.

When installing these rings, pay close attention to the manufacturer's instructions to ensure proper seating and sealing. Because these are gapless top rings, they require careful handling and precise installation to function as intended. Remember that these rings are not CARB approved and cannot be shipped to California. Always ensure your engine build plans align with local emissions regulations.
