Product Details

Raybestos R-Line focuses on direct-fit brake service parts for everyday repair work, and the 782815R rotor follows that approach with conventional rotor construction and application-specific dimensions. It is a conventional, drum-in-hat style rotor with a 2.087-inch overall height and 3 miscellaneous holes as listed in the product data. This rotor is specified for rear use on select Jeep Grand Wagoneer, Jeep Wagoneer, Jeep Wagoneer L, and Ram 1500 models, including 2021-2024 Ram 1500 rear applications and 2022-2024 Jeep Grand Wagoneer rear applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Service Issues

• Rear brake pulsation from rotor wear or thickness variation
• Brake noise caused by worn or heat-affected rotor surfaces
• Reduced braking consistency from a rotor below discard thickness
• Service replacement needs on rear brake systems for Jeep Grand Wagoneer and Ram 1500
• Rotor replacement after inspection shows scoring, corrosion, or uneven wear
