Product Details and Specifications

This DuraGo disc brake rotor (part number BR31373-01) is made from cast iron, a material known for its durability and effective heat management during braking. The rotor features a vented construction that allows air to flow between the rotor surfaces, helping to dissipate heat and reduce the risk of brake fade during extended use. The rust-resistant coating helps protect the rotor from corrosion, which is especially beneficial in humid or wet environments.

The rotor measures 10.94 inches (278 mm) in outside diameter and has an overall height of 1.92 inches (48.7 mm). It includes five mounting bolt holes with a bolt circle diameter of 4.5 inches (114.3 mm) and a center hole diameter of 2.83 inches (72 mm). The nominal thickness is 0.98 inches (25 mm), with a discard thickness of 0.91 inches (23 mm), indicating when the rotor should be replaced to maintain safe braking performance. This rotor is a conventional, non-directional type without cross-drilling or slotting.

Compatible Vehicles and Applications
