Detailed Product Description

The DuraGo BR55065 disc brake rotor is constructed from full cast iron, providing consistent heat dissipation and structural integrity under braking conditions. This solid rotor design is conventional, without slots or cross-drilled holes, which suits vehicles requiring standard braking components without additional cooling features. The rotor measures 11.06 inches in outside diameter and has a nominal thickness of 0.43 inches, with a discard thickness of 0.35 inches, ensuring it meets OEM specifications for safe replacement intervals.

With five mounting bolt holes arranged on a 4.65-inch bolt circle diameter, this rotor fits securely on compatible hubs. The center hole diameter of 2.79 inches allows proper alignment on the vehicle’s hub assembly. The non-directional brake surface simplifies installation, as the rotor can be mounted in either orientation without affecting performance.
