The rotor features a plain disc finish with a zinc silver hat finish that provides enhanced rust resistance, extending the rotor's service life. The drilled and slotted surface improves heat dissipation and helps evacuate brake dust and gases, which can improve braking performance and reduce fade during heavy use. The rotor’s nominal thickness is 12 mm, with a discard thickness of 10.4 mm, ensuring clear service limits for safe operation. The 5-bolt hole pattern with a 127 mm bolt circle diameter matches the factory specifications for these Jeep models, ensuring proper fitment and installation.\u003c\/p\u003e\u003ch2\u003eDFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance braking efficiency and rotor cooling. This product line is designed to meet the demands of drivers who require consistent braking performance, especially in off-road or heavy-duty conditions typical for Jeep Wrangler and Wrangler JK vehicles. The silver zinc coating on the rotor hat adds a layer of corrosion protection, which is important for vehicles exposed to harsh environments.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Jeep Wrangler and Wrangler JK models requiring 316 mm diameter rotors\u003c\/li\u003e\n\u003cli\u003eHelps reduce brake fade during extended braking or off-road use\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eMinimizes brake dust buildup for cleaner braking surfaces\u003c\/li\u003e\n\u003cli\u003eProvides corrosion resistance to extend rotor lifespan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (10.4 mm) before installation\u003c\/li\u003e\n\u003cli\u003eVerify bolt hole pattern and bolt circle diameter (5 bolts, 127 mm) for compatibility\u003c\/li\u003e\n\u003cli\u003eClean rotor surface before installation to remove any protective coatings or debris\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for lug nuts to avoid rotor damage\u003c\/li\u003e\n\u003cli\u003eInspect brake pads for wear and replace if necessary to ensure optimal rotor performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-42029L rotor to meet OEM specifications for Jeep Wrangler and Wrangler JK vehicles.
