Detailed Product Description

The DuraGo BR55029 disc brake rotor is constructed from full cast iron, providing a robust and heat-resistant braking surface. Its vented design allows air to circulate between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade under heavy loads. With a nominal thickness of 1.43 inches and a discard thickness of 1.37 inches, this rotor maintains optimal performance throughout its service life. The rotor measures 13.86 inches in outside diameter and features five mounting bolt holes arranged on a 6.34 inch bolt circle diameter, ensuring precise fitment on Chevrolet and GMC P30 and P3500 vehicles. The non-directional brake surface allows for installation on either side without performance loss, and the conventional rotor design is compatible with standard brake caliper setups.

Compatible Vehicles and Applications

This rotor is compatible with the following vehicles:

• Chevrolet P30
• GMC P30
• Chevrolet P3500
• GMC P3500

It is designed for use in commercial and heavy-duty braking systems where reliable stopping power and rotor durability are critical.

Common Issues Addressed by DuraGo BR55029

• Brake rotor warping due to heat buildup
• Reduced braking efficiency from worn or thin rotors
