The drilled and slotted surface design helps to reduce brake fade by allowing gases and debris to escape, while the vented rotor construction improves airflow to maintain optimal operating temperatures. The zinc silver hat finish provides corrosion resistance, extending the rotor's service life, especially in harsh environments.\u003c\/p\u003e\u003cp\u003eWith an outside diameter of 317.5 mm and a nominal thickness of 32.8 mm, this rotor meets OEM specifications for Chevrolet and GMC heavy-duty trucks and vans, including the C20 Suburban, C3500, G30, P20, and R2500 Suburban models. The directional brake surface ensures proper installation orientation for consistent braking performance. The rotor features eight bolt holes with a 9\/16-18 diameter and a bolt circle diameter of 165.1 mm, matching factory mounting requirements.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eChevrolet C20, C20 Suburban, C30, C2500, C2500 Suburban, C3500\u003c\/li\u003e\n\u003cli\u003eGMC G30, P20, P30, P2500, P3500, R20, R20 Suburban, R2500, R2500 Suburban\u003c\/li\u003e\n\u003cli\u003eDesigned for heavy-duty trucks and vans requiring vented, drilled, and slotted rotors\u003c\/li\u003e\n\u003cli\u003eIdeal for vehicles experiencing brake fade, overheating, or reduced stopping power\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 as indicated on the rotor. Verify bolt hole alignment with the vehicle’s hub using the 8-bolt pattern and 165.1 mm bolt circle diameter. Check rotor thickness before installation; replace if below the discard thickness of 30.86 mm. Clean the rotor surface to remove any protective coatings or debris before mounting to ensure optimal brake pad contact.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor line to meet or exceed OEM standards for fit, form, and function.
