The drilled and slotted design helps to reduce brake fade by allowing gases and heat to escape, while the directional surface pattern optimizes water and debris evacuation. This rotor line is finished with a zinc silver hat and a rust-resistant coating to protect against corrosion, making it suitable for heavy-duty applications such as those found in Ford E-Series vans.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented, which means it has internal vanes between the rotor faces to increase airflow and cooling. The rotor’s outside diameter measures 345 mm, with an overall height of 144 mm and a center hole diameter of 123.8 mm. It features eight bolt holes with a bolt circle diameter of 165.1 mm, matching the stud\/lug hole circle diameter for proper fitment. The nominal thickness is 40 mm, with a discard thickness of 38.4 mm, indicating when the rotor should be replaced to maintain safe braking performance.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped rotors on Ford E-150, E-250, and E-350 Super Duty\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet or debris-prone environments\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eSupports safe braking under heavy load or towing conditions\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 38.4 mm before installation. The rotor is directional, so install it following the indicated rotation direction for optimal performance. Use the correct torque specifications for the 9\/16-18 bolt holes and verify compatibility with the vehicle’s hub assembly. Clean the rotor surface before mounting to remove any protective coatings or contaminants.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for Ford E-Series vans. The rust-resistant zinc silver hat finish extends rotor life by protecting against corrosion. While no specific warranty information is provided, the rotor’s design and materials support durability and consistent braking performance under normal operating conditions.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794145050805,"sku":"HBHR-631-54209R","price":275.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63154209R_Fro.jpg?v=1774641563","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-54209r-disc-brake-rotor-front-right","provider":"PartCatalog","version":"1.0","type":"link"}
