Detailed Description

DuraGo BR55023 is engineered as a direct replacement front rotor and hub assembly for 1990-1994 Chevrolet C3500 and 1990-1994 GMC C3500 DRW front brake service. The vented rotor design, 317.5 mm outside diameter, and 39 mm nominal thickness support proper brake system geometry for heavy-duty front axle applications. With an 8-lug hub pattern, M14 x 1.5 studs, and included bearing cups, this assembly is built to simplify front-end brake repair while maintaining the required hub and rotor interface. This part number, BR55023, is a practical choice when servicing front brake wear on Chevrolet C3500 and GMC C3500 trucks that use the specified DRW configuration.

What It Helps Address

• Front brake pulsation caused by rotor wear or thickness variation
• Hub and rotor service when the existing assembly is worn or damaged
• Brake noise related to uneven rotor surface condition
• Loose or compromised wheel mounting from worn hub components
• Brake performance loss from excessive rotor discard thickness

Installation Notes and Tips

Verify vehicle year, make, model, and DRW configuration before installation. Confirm rotor dimensions, bearing fitment, and stud pattern against the original assembly. Clean all mating surfaces thoroughly and inspect related brake components, including pads, bearings, and seals, before reassembly. Because this rotor is non-directional and vented, proper seating and torque procedures are important for even brake performance. Fits 1990-1994 Chevrolet C3500, front. Fits 1990-1994 GMC C3500, front.
