Detailed Description

This Dynamic Friction DFC Brake Rotor is engineered for front brake service on heavy-duty trucks that require a vented 317 mm rotor. The dimensions are important for proper rotor-to-hub and pad alignment, especially on vehicles such as the Chevrolet K3500 and GMC K3500 with dual rear wheels, plus Dodge Ram 2500 and Ram 3500 front axle configurations listed in the fitment data. If you are replacing a worn front rotor on a Dodge Ram 2500 or Ram 3500, part number 600-40052 provides the specified diameter, thickness range, and bolt pattern needed for the application.

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

What This Rotor Helps Address

• Front brake pulsation caused by rotor wear or thickness variation
• Brake noise related to uneven rotor surfaces
• Reduced braking performance from a worn vented rotor
• Service replacement for rotors that no longer meet discard thickness
• Fitment issues on heavy-duty trucks requiring a 317 mm front rotor

Installation Notes and Tips

Verify rotor diameter, bolt hole count, and hub dimensions before installation. This rotor is listed for front position use only, and fitment varies by axle configuration on some Dodge Ram 2500 and Ram 3500 models. Inspect pads, calipers, and hub surfaces during brake service to help ensure even contact and proper rotor seating. Confirm the vehicle’s brake setup matches the listed notes, including dual rear wheels or Dana 60 front axle details where specified.
