CP Piston 3.571in Bore 1.5mm Top Ring 1.5mm 2nd Ring 3.0mm Oil Ring Set (Single Cylinder)

This set of piston rings from CP Pistons is built with specific dimensions: a 3.571-inch bore size, a 1.5mm top ring, a 1.5mm second ring, and a 3.0mm oil ring. These precise measurements are crucial for ensuring a proper seal between the piston and the cylinder wall, which directly impacts engine performance and efficiency. The thinner top and second rings are designed to reduce tension and friction, potentially leading to improved engine response.

When rebuilding or refreshing an engine, selecting the correct piston rings is vital for proper cylinder sealing. These rings are intended for single-cylinder applications, meaning they are sold individually for one piston.
