- 6-Lug Brake Rotor Compatibility Range： ※※The High-Profile Caliper (Front Hub Puller) is designed specifically for 5-lug or 4-lug brake disc configurations.

- How to Verify Compatibility The Mounting Bolt Hole Circle Diameter (PCD) can typically be obtained from your vehicle manufacturer or brake Rotor supplier. If this information is unavailable, for 4-hole or 6-hole brake Rotor, you can directly measure the center-to-center distance between two opposite bolt holes, which is the PCD. For 5-hole brake Rotor, you can measure the center-to-center distance between two adjacent bolt holes: For front hub brake Rotor: The center-to-center distance should be 62–72 mm (2.44–2.83 inches). For rear hub brake Rotor: The center-to-center distance should be 65–80 mm (2.56–3.15 inches). Ensure your vehicle’s specifications match these ranges before purchasing.
