What is the purpose of piston rings?

Piston rings serve a few critical functions. They seal the combustion chamber to maintain compression, regulate oil consumption by scraping excess oil off the cylinder walls, and help transfer heat from the piston to the cylinder wall for cooling.

What does the sizing (1.2mm, 1.2mm, 2.8mm) refer to?

These measurements refer to the thickness of each ring. The first two numbers are for the compression rings (top and second rings), and the third number is for the oil control ring. This specific sizing is important for proper fitment with your pistons and cylinder bore.

Are these rings suitable for all engine rebuilds?

This set is designed for an 87.60mm bore. You must verify that this bore size matches your engine's specifications. Additionally, these rings are not CARB approved and cannot be shipped to California.

Product Details

If you're rebuilding the top end of your engine, getting the right piston rings is crucial for a good seal and proper compression. This set from Manley Performance is designed for an 87.60mm bore, which is a common size for many performance and stock rebuilds. These rings are what seal the combustion chamber, keeping power where it belongs and preventing oil from getting into the burn area.

Manley is known for making well-built internal engine components, and this ring set is no exception. The ring sizes are 1.2mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil control ring. This specific sizing is important for matching your pistons and cylinder bore for optimal performance and longevity. Getting the ring gap and tension just right is key during installation to ensure a good seal right from the start.

This set includes rings for a complete set of four cylinders. Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for proper installation procedures and ring gap specifications.
