It features a vented design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during heavy use. The rotor’s nominal thickness of 1.185 inches ensures a robust braking surface, while the discard thickness of 1.063 inches indicates when replacement is necessary to maintain safe braking performance. The overall height of 2.040 inches and outside diameter of 10.830 inches are engineered to fit precisely with the vehicle’s brake system. The rotor includes five mounting bolt holes with a 4.528 inch bolt circle diameter, ensuring secure installation. Its conventional design is compatible with drum-in-hat brake configurations commonly found on these models.\u003c\/p\u003e\u003ch2\u003eAbout the Raybestos Specialty - Truck Product Line\u003c\/h2\u003e\u003cp\u003eThe Specialty - Truck line from Raybestos focuses on heavy-duty and specialty brake components designed to meet the demands of truck and SUV applications.
