Detailed Specifications and Product Line Information

This Raybestos rotor belongs to the Specialty - Truck; Coated Rotor product line, which focuses on providing rotors specifically designed for truck applications that demand enhanced durability and corrosion resistance. The coating on this rotor helps protect against rust and environmental wear, making it suitable for trucks operating in varied conditions. The vented design improves heat dissipation during braking, reducing the risk of brake fade under heavy loads.

With 10 mounting bolt holes and a bolt hole circle diameter of 11.250 inches, this rotor is engineered to fit a range of truck models requiring these specifications. The smooth surface finish supports consistent brake pad contact, contributing to stable braking performance.

Applications and Problem Solving

• Replacement for worn or warped rotors on compatible truck models
• Addresses brake fade caused by overheating during heavy-duty use
• Prevents corrosion-related rotor damage in harsh environments
• Restores proper rotor thickness to maintain braking efficiency
• Ensures secure mounting with 10-bolt hole configuration for specific trucks

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.320 inches before installation. Verify compatibility with your truck’s mounting bolt pattern of 10 holes and 11.250-inch bolt circle diameter. Clean the hub surface before mounting to prevent uneven rotor seating. Use proper torque specifications for mounting bolts to avoid rotor warping.

Quality Assurance and Warranty

Raybestos rotors are manufactured to meet or exceed OEM standards for durability and performance. The Specialty - Truck; Coated Rotor line undergoes rigorous quality control to ensure consistent thickness, balanced venting, and corrosion resistance. Warranty details should be confirmed with the supplier or manufacturer, as they may vary by application and region.
