Product Details and Specifications

The DuraGo BR901678-01 rotor features a full cast iron construction that balances durability with effective heat management. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under demanding conditions. The rotor measures 12.99 inches (330 mm) in outside diameter and has an overall height of 2.72 inches (69 mm). It includes five mounting bolt holes with a bolt circle diameter of 4.72 inches (120 mm) and a center hole diameter of 2.95 inches (75 mm). The nominal thickness is 0.79 inches (20 mm), with a discard thickness of 0.72 inches (18.4 mm), indicating when the rotor should be replaced to maintain safe braking performance. The rotor surface is non-directional, allowing for flexible installation without concern for rotation direction.
