What size are the front rotors on a Dodge Journey?
The front rotors on most Dodge Journey models are 12 inches in diameter (about 304 mm). Exact size can vary by year, engine, and trim, so it’s important to verify for your specific vehicle.
Rotor size basics for the Journey
Brake rotor sizes can change slightly depending on generation, engine configuration, and optional braking packages. In general, the Dodge Journey used around a 12-inch front rotor in common configurations, with very close variations (roughly 11.8–12.0 inches) depending on the exact model year.
Why size variation happens
Variations arise from differences in braking components, caliper design, and manufacturing changes over the vehicle’s production run. Even small diameter differences can affect compatibility with pads and calipers.
How to confirm the exact size for your vehicle
To be precise, use these verification methods before sourcing parts.
- Look up the vehicle’s VIN in the official Mopar/Chrysler parts catalog or contact a Dodge dealership to retrieve the exact rotor specification for your car.
- Check the owner's manual or service manual for the correct front rotor size and part number for your year and engine.
- Physically inspect and measure the rotor: with the wheel removed, measure the diameter across the braking surface from edge to edge through the center of the rotor.
- When replacing, make sure you match both diameter and rotor thickness as specified, and ensure compatibility with your calipers and mounting hardware.
Following these steps will help ensure you order the correct front rotor for your Dodge Journey.
Maintenance considerations
Rotor size is just one aspect of braking maintenance. When replacing rotors, also consider rotor thickness, runout, wear patterns, and pad material to maintain optimal braking performance and safety.
Summary: The Dodge Journey commonly uses 12-inch front rotors, but exact size varies by year, engine, and trim. Always verify with VIN-based parts catalogs or by measuring the rotor on your vehicle to ensure you select the correct part.
