Installation Notes and Tips

Confirm rear-position fitment, bolt circle, and pilot diameters before installation. Inspect the mating surfaces, fasteners, and brake components for wear or damage, and verify that the hub seats fully during assembly. Because the ABS sensor is not included, reuse or source the correct sensor arrangement for the vehicle if equipped.
