Product Details and Specifications

The DuraGo BR901944-01 rotor is constructed from cast iron, a material known for its excellent heat dissipation and durability under heavy braking conditions. Its full cast design ensures consistent strength and resistance to warping. The rotor features a vented design, which allows air to flow between the rotor surfaces, reducing heat buildup and improving braking efficiency. A rust-resistant coating is applied to the rotor surface to help prevent corrosion and extend the rotor's lifespan, especially in harsh weather conditions.

This rotor is a drum-in-hat type, integrating a drum brake surface within the rotor hat area, compatible with the rear braking system of Ram ProMaster models. It includes five mounting bolt holes arranged on a 5.12-inch (130 mm) bolt circle diameter, with each hole measuring 0.7 inches (17.8 mm) in diameter. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Ram ProMaster 1500 disc brake replacement
• Ram ProMaster 2500 brake rotor upgrade
• Ram ProMaster 3500 vented rotor installation
• Ram ProMaster EV rear brake rotor replacement
• Addressing rotor wear, warping, and corrosion issues

Installation Notes and Tips

When installing the DuraGo BR901944-01 rotor, ensure the mounting surface is clean and free of debris to promote proper fitment. Verify the rotor thickness before installation; replace if below the discard thickness of 0.78 inches (19.9 mm). Since this rotor is non-directional, it can be installed on either side without affecting performance. Use the correct torque specifications for the 5 mounting bolts to avoid rotor distortion.
