This configuration helps improve heat dissipation and reduces brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking a balance between performance and durability in their braking components.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented to allow better airflow, which helps maintain optimal operating temperatures during braking. The drilled and slotted surface design aids in removing brake dust, gases, and water from the rotor surface, improving pad contact and braking efficiency. The rotor has a nominal thickness of 26.1 mm and a discard thickness of 24.5 mm, indicating when replacement is necessary. The rotor’s hat is coated with a rust-resistant zinc silver finish, while the disc surface is plain, providing a clean and functional appearance. The rotor features five bolt holes with a 1\/2-20 diameter and a bolt circle diameter of 114.3 mm, matching the stud\/lug hole circle diameter for secure mounting. The overall height and height are both 108 mm, with an outside diameter of 261 mm and a center hole diameter of 63.6 mm, ensuring proper fitment on compatible vehicles.\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 Ranger and Mazda B-series trucks\u003c\/li\u003e\n\u003cli\u003eImproves braking performance by reducing heat buildup and brake fade\u003c\/li\u003e\n\u003cli\u003eHelps eliminate brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eResists rust and corrosion to extend rotor service life\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking under wet or dusty conditions due to drilled and slotted 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 24.5 mm before installation. Clean the hub surface and mounting area to prevent runout and ensure proper rotor seating. Use the correct torque specifications for the 1\/2-20 bolts and verify the rotor’s directional orientation matches the vehicle’s rotation. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver coating helps protect against corrosion, contributing to longer rotor life. While no specific warranty information is provided, the product is designed for durability and consistent braking performance on compatible Ford and Mazda trucks.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51794135580853,"sku":"HBHR-631-54139R","price":123.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63154139R_Fro.jpg?v=1774641544","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-54139r-disc-brake-rotor-front-right","provider":"PartCatalog","version":"1.0","type":"link"}
