CP Pistons 85.5mm Bore PVD Ring Set

If you're rebuilding the top end of your engine and need a fresh set of piston rings, this 85.5mm bore set from CP Pistons is a solid option. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. A good set of rings ensures your engine runs efficiently and lasts.

This particular set features PVD coating on the top ring, which is a tough surface treatment that helps reduce friction and wear, especially under demanding conditions. This can lead to improved performance and longer ring life. The set is designed to fit pistons with an 85.5mm bore, a common size for many performance and stock engine builds. Make sure to verify your piston bore size before ordering.
