Detailed Description

DuraGo BR901450 is a rear brake rotor for Ram trucks that require a vented, drum-in-hat style rotor with an 8-lug pattern. It measures 14.09 inches in outside diameter and uses a non-directional braking surface to support even pad contact during service. This rotor is a direct-fit option for 2011-2025 Ram 2500 rear applications, 2011-2018 Ram 3500 rear applications, 2019-2024 Ram 3500 rear SRW applications, 2025 Ram 3500 rear DRW applications with 358 mm rotor diameter, 2012 Ram 1500 rear 8 lug, and 2009-2010 Dodge Ram 2500 and Ram 3500 rear applications. This part cross-references 52122184AA and 68188899AA for the same application. The BR901450 part number is a practical match for service work where OE-style dimensions and brake rotor geometry matter.

Common Problems This Rotor Can Address

• Rear brake pulsation from a worn or out-of-spec rotor
• Brake noise caused by uneven rotor surface wear
• Reduced braking consistency from excessive rotor thickness loss
• Service issues on Ram 2500 and Ram 3500 rear brake systems with drum-in-hat rotors
• Fitment concerns when replacing an 8-lug rear disc brake rotor

Installation Notes and Tips

Verify rotor diameter, bolt pattern, and rear axle/brake configuration before installation. Confirm the vehicle uses a drum-in-hat rear rotor and check discard thickness against the existing part before reuse or replacement. Clean the hub mounting surface thoroughly to help prevent runout-related brake complaints. Always inspect pads, calipers, and parking brake components during rotor service on Ram 2500, Ram 3500, and Ram 1500 rear brake applications.
