Raybestos 680508 Specialty Truck Front Disc Brake Rotor

The Raybestos 680508 Specialty Truck Disc Brake Rotor is engineered specifically for heavy-duty truck applications, delivering superior performance and noise reduction for demanding front brake systems. Part of the Raybestos Specialty line, this rotor is built to perform in truck and medium-duty applications where noise-prone conditions are a concern.

Key Features:

• Vehicle-specific cooling vane configurations matched to OE specifications for optimal heat dissipation and reduced brake fade
• Application-specific cast iron metallurgy that dampens noise and keeps brakes running cool, quiet, and vibration-free
• Vented rotor design with 6 mounting bolt holes for enhanced cooling performance
• 13.78-inch outside diameter with 1.339-inch nominal thickness
• 1.26-inch minimum discard thickness for extended service life
• 3.54-inch center hole diameter for precise hub fitment
• Non-directional brake surface allows for flexible installation
• Meets SAE standards for tensile strength with G3000-qualified material
• Tight lateral runout of 0.002 inches or less reduces pedal pulsation and extends pad life
• Installation-ready with turned finish that minimizes break-in noise

Designed for Class 1 through Class 8 truck applications, this rotor provides reliable stopping power and extended service life in heavy-duty conditions. The advanced metallurgy and precision engineering ensure consistent, predictable braking performance while addressing common noise issues in truck brake systems.

Specifications: Cast iron construction, conventional (non-drum-in-hat) design, 6-stud configuration, 1.95-inch overall height. Cross-references multiple OEM part numbers including Ford 7L1Z1125A, 8L1Z1125A, 9L1Z1125A, AL3Z1125B, and CL3Z1125B.
