Installation Notes and Tips

Verify rear fitment by year, make, model, and brake configuration before installation. Confirm the 4-stud, 100 mm bolt circle layout and compare pilot diameters to the original hub. Because the ABS sensor is not included, applications requiring a sensor must retain or source the correct separate component. For best results, inspect related rear suspension and brake parts during service.
