About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and this piston ring set is a great example of that. If you're rebuilding the engine in your Chevy LT1, these rings are designed to fit a 4.080-inch bore. They feature a 1.2mm thick top ring and a 3.0mm steel oil control ring, which are common dimensions for many LT1 builds. This set includes enough rings for a complete set of 8 cylinders.

The construction here is solid. The top ring is made from steel, offering good durability and heat resistance for performance applications. The oil ring is also steel, helping to control oil consumption and maintain proper lubrication. These rings are built to seal well against the cylinder wall, which is crucial for compression and overall engine health. When installing, make sure to follow the manufacturer's recommended gap settings for your specific application to ensure optimal performance and longevity.
