This design helps reduce brake fade and maintain consistent stopping power. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving environments.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a plain disc finish with a directional surface type that is both drilled and slotted. The rotor's nominal thickness is 22 mm, with a discard thickness of 20.4 mm, ensuring safe replacement intervals. The rotor includes six bolt holes, each 17 mm in diameter, arranged on a 139.7 mm bolt circle diameter, matching the Ram 1500 and 1500 Classic specifications. The zinc silver hat finish offers rust resistance, protecting the rotor from corrosion and environmental wear. With an outside diameter of 375 mm and a height of 53.44 mm, this rotor fits precisely to maintain optimal braking performance.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eImproves braking performance for Ram 1500 and 1500 Classic trucks\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during heavy braking or towing\u003c\/li\u003e\n\u003cli\u003eEnhances heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eResists rust and corrosion for longer rotor life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent brake pad contact with slotted and drilled design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 20.4 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the vehicle’s hub using the 139.7 mm bolt circle diameter and six bolt holes. Proper torque specifications should be followed to avoid rotor warping.
