This configuration helps reduce brake fade by improving heat dissipation and removing debris from the rotor surface. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life in harsh environments.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a 330 mm outside diameter and an overall height of 85.7 mm, making it suitable for heavy-duty applications. The rotor is vented to allow better airflow, which helps maintain optimal operating temperatures during braking. The drilled and slotted surface design improves water and gas evacuation, enhancing brake pad contact and reducing the risk of brake fade. The directional surface ensures the rotor is installed correctly for maximum performance. With eight bolt holes measuring 16.5 mm in diameter and a bolt circle diameter of 165.1 mm, this rotor fits securely on compatible Chevrolet, GMC, and Hummer models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplaces worn or warped rotors on Chevrolet Silverado 1500 HD and GMC Sierra 2500 HD\u003c\/li\u003e\n\u003cli\u003eImproves braking performance for heavy-duty vehicles like the Hummer H2 and Chevrolet Avalanche 2500\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during towing or heavy load conditions\u003c\/li\u003e\n\u003cli\u003eMinimizes rust and corrosion with zinc silver coating for extended rotor life\u003c\/li\u003e\n\u003cli\u003eEnhances braking consistency in wet or dusty environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 16.5 mm bolt hole diameter and 165.1 mm bolt circle diameter. Check rotor thickness before installation; replace if below the discard thickness of 26.5 mm. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-48039R rotor to meet or exceed OEM specifications for fit, form, and function.
