• Zinc Coating: Protective zinc finish guards against corrosion and rust, extending rotor life and maintaining appearance
• Direct OEM Replacement: Machined to factory specifications for a no-modification, bolt-on installation
• Left-Side Specific (Driver's Side): The "L" suffix designates this as the left/driver's side rotor — sold individually
• Vented Rotor Design: Internal vane structure promotes airflow for continuous cooling during use
