Description

These piston rings are pre-lapped to seat immediately, virtually eliminating break-in time. The compression rings feature a barrel-faced contact area for more efficient compression and optimized gap chamfering to reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and the CP-20 oil ring assemblies offer an exclusive 20-degree ear angle for superior side seal against the cylinder wall. The oil ring expander has a special chemical polish for enhanced oil drain back.
