This product line is designed to reduce brake fade and maintain consistent stopping power, particularly suited for trucks like the Ram 1500 series. The silver zinc coating on the rotor hat provides corrosion resistance, helping to extend the rotor's service life in various driving environments.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a plain disc finish with a directional surface type that includes both drilled holes and slots. The rotor's nominal thickness is 22 mm, with a discard thickness of 20.4 mm, ensuring safe replacement intervals. The rotor is designed with 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 rotor's outside diameter is 375 mm, and it has a height of 53.44 mm, with a center hole diameter of 78.42 mm to ensure proper hub alignment.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Ram 1500 and 1500 Classic\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eAddresses brake noise and vibration issues caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance under load or towing conditions\u003c\/li\u003e\n\u003cli\u003eProtects against rust and corrosion with zinc silver coating for longer rotor life\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 prior to mounting. Verify bolt hole alignment with the vehicle hub using the 139.7 mm bolt circle diameter and six bolt holes. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-40121L rotor to meet OEM specifications for fit and function on Ram 1500 and 1500 Classic models.
