Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 1.024 inches. Clean the rotor surface to remove any protective coatings or debris before mounting. Verify the 5-lug bolt pattern and 4.5 inch bolt circle diameter match the vehicle hub. Since this rotor does not include bearings or an ABS tone ring, reuse existing components if applicable. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
