Advanced Engineering Features:

• SAE 9254 high alloy steel base material provides superior tensile and yield strength, extended fatigue resistance, and increased material hardness
• Chrome-faced compression rings with barrel-faced contact area optimize compression efficiency and reduce blow-by
• Pre-lapped rings seat immediately, virtually eliminating break-in time for faster installation
• CNC-controlled gap chamfer ensures precise compression sealing and minimizes power loss
• CP-20 oil ring assemblies feature an exclusive 20-degree ear angle for superior side seal in the piston oil ring groove
• Special chemical polish on oil ring expander enhances oil drain-back and control
