The drilled and slotted surface pattern improves brake pad bite and helps reduce brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life especially in environments prone to rust. This product line is tailored for vehicles requiring durable, vented rotors with directional braking surfaces.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s nominal thickness is 40 mm, with a discard thickness of 38.4 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor measures 345 mm in outside diameter and 144 mm in overall height, fitting the specified Ford models precisely. The directional slotted and drilled surface enhances water and gas evacuation, improving braking consistency in wet or high-temperature conditions.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake 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-duty or towing applications\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance in wet or dusty environments\u003c\/li\u003e\n\u003cli\u003eAddresses rotor corrosion issues with rust-resistant zinc silver hat finish\u003c\/li\u003e\n\u003cli\u003eSupports directional braking surface requirements for specific vehicle brake systems\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. Clean the rotor surface to remove any protective coatings or contaminants. Verify bolt hole alignment with the 8-hole, 9\/16-18 bolt pattern and 165.1 mm bolt circle diameter. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. This rotor is directional; install with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for Ford E-150, E-250, and E-350 Super Duty vehicles. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the rotor is designed for reliable, professional-grade braking performance consistent with industry standards.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794145018037,"sku":"HBHR-631-54209L","price":275.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63154209L_Fro.jpg?v=1774641563","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-54209l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
