Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The rotor surface is both drilled and slotted, which assists in channeling away brake dust, gases, and water, maintaining consistent brake pad contact. The directional brake surface ensures optimal performance when installed in the correct orientation.

The rotor’s nominal thickness is 24 mm, with a discard thickness of 22.6 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver coating on the rotor hat provides rust resistance, extending the rotor’s service life. With six bolt holes sized at 13.7 mm diameter and a bolt circle diameter of 114.3 mm, this rotor fits securely on compatible Dodge models.
