Frequently Asked Questions

Q: What does the "LB" marking on this rocker arm signify?

A: The LB marking indicates the specific manufacturing batch and specification for this Ducar OEM-quality rocker arm, ensuring it meets the exact leverage and durability standards required for the CL-1075 valvetrain setup.
