What is the purpose of different ring thicknesses (1.5mm, 1.5mm, 3mm)?

The different thicknesses are optimized for specific functions. The thinner top and second rings are designed for efficient sealing and reduced friction. The wider oil ring is responsible for scraping excess oil from the cylinder walls to prevent it from entering the combustion chamber.

Are these rings suitable for a stock LS engine rebuild?

These rings are built for a 4.130-inch bore, which is often used in modified or stroker LS engines. While they are well-built, it's important to confirm this bore size matches your specific engine build to ensure proper fitment and performance.

What does 'Not CARB approved' mean for this product?

This means the product does not meet the emissions standards set by the California Air Resources Board (CARB). As a result, it cannot be legally sold or shipped to California.

About this part

Product Details

If you're rebuilding the top end of your Chevy LS engine, getting the right piston rings is crucial for sealing and performance. This set from Manley Performance is built for a 4.130-inch bore, a common size for many LS engine builds looking for a bit more displacement. These rings are designed to create a tight seal between the piston and cylinder wall, which is essential for proper compression, preventing oil from entering the combustion chamber, and efficiently transferring heat.

This particular set features steel top rings with a 1.5mm thickness, a second ring at 1.5mm, and a 3mm oil ring. Steel top rings are known for their strength and ability to handle higher cylinder pressures and temperatures compared to cast iron, making them a solid choice for performance applications. The specific ring land dimensions ensure a precise fit on the piston, which is key for longevity and preventing blow-by. Manley is a well-known name in performance engine components, and this set reflects their focus on durable parts for demanding builds.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Ensure you check your specific engine build requirements to confirm these dimensions are correct for your application.
