Detailed Product Description

The DuraGo BR55031 rotor is constructed from full cast iron, providing a robust and heat-resistant braking surface suitable for heavy-duty applications. Its vented design enhances airflow to reduce heat buildup during braking, which helps maintain consistent performance and reduces the risk of brake fade. The rotor measures 13.58 inches in outside diameter and 4.37 inches in overall height, matching OEM specifications for Chevrolet P30 and GMC P3500 trucks. With a nominal thickness of 1.44 inches and a discard thickness of 1.37 inches, this rotor ensures a long service life while maintaining safety standards. The 10 mounting bolt holes and 7.26-inch bolt circle diameter provide secure installation, and the non-directional brake surface allows for flexible rotor placement without affecting performance.

Compatible Vehicles and Applications

• Chevrolet P30 heavy-duty truck
• GMC P3500 heavy-duty truck
• Replacement rotor for disc brake systems requiring 10-bolt mounting
• Ideal for vehicles needing vented rotors to manage heat during heavy braking
• Suitable for conventional brake rotor setups without ABS tone rings

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.37 inches) before installation
• Clean mounting surface to prevent rotor runout and vibration
• Use proper torque specifications for the 10 mounting bolts to secure the rotor
• Check compatibility with existing brake pads and calipers on Chevrolet P30 and GMC P3500
