What is the purpose of different ring sizes (1.5mm x 1.5mm x 3mm)?

These dimensions refer to the height of the top compression ring (1.5mm), the second compression ring (1.5mm), and the oil control ring (3mm). This specific combination is often chosen for performance builds to optimize sealing and oil control.

Are these piston rings suitable for a stock rebuild?

While these rings are well-built, their specific dimensions and steel construction are often favored for performance or modified LS engines. For a completely stock rebuild, it's always best to verify if these dimensions match the original specifications or your intended build goals.

About this part

Product Details

When you're rebuilding the top end of your Chevy LS engine, getting the piston rings right is crucial for proper sealing and performance. These steel top piston rings from Manley are designed for a 4.135-inch bore, a common size for many LS engine builds. They feature a specific ring land configuration: 1.5mm for the top ring, 1.5mm for the second ring, and 3mm for the oil ring, which is a popular setup for performance applications.

Manley Performance is known for making well-built engine components, and these piston rings are no exception. Made from steel, they offer good durability and resistance to wear, especially in higher-performance or boosted applications where stock rings might struggle. Getting the correct ring tension and sealing is key to preventing blow-by and ensuring your engine makes the power it's supposed to.

This set includes eight top piston rings, enough for a complete V8 engine. Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and the manufacturer's installation guide for proper ring gap and installation procedures.
