This rotor line features a plain disc finish combined with a zinc silver hat finish that provides corrosion resistance. The drilled and slotted surface pattern is directional, designed to improve brake pad bite and reduce heat buildup, which is critical for maintaining braking efficiency under demanding conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 11 mm, ensuring a clear service limit for safe operation. The rotor’s outside diameter measures 285 mm, with an overall height of 57.9 mm. It includes five bolt holes, each with a diameter of 16.6 mm, arranged on a 114.3 mm bolt circle diameter, matching the factory specifications for Jeep Liberty, TJ, and Wrangler models. The center hole diameter is 72 mm, allowing for proper hub fitment. The zinc silver hat finish and rust-resistant coating help protect against corrosion, extending the rotor’s service life.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake rotors on Jeep Liberty, TJ, and Wrangler\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during heavy braking\u003c\/li\u003e\n\u003cli\u003eSlotted and drilled design helps remove brake dust and gases for consistent pad contact\u003c\/li\u003e\n\u003cli\u003eDirectional surface enhances braking performance and pad bite\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant coating prevents rust buildup in harsh environments\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 11 mm before installation. Clean the rotor surface to remove any protective coating or contaminants prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 114.3 mm bolt circle pattern. Proper torque specifications should be followed to avoid rotor warping. This rotor is designed for direct replacement on compatible Jeep models without modification.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM standards for fit, form, and function.
