What size are the rotors on a Dodge Charger?

There isn’t a single rotor size for all Dodge Charger models—the diameter varies by year and trim. In general, front rotors run roughly 12.6 to 15 inches, while rear rotors are roughly 11.5 to 13 inches, depending on configuration.

The Charger has been produced in multiple generations with a wide range of brake packages—from everyday, economical setups to high-performance Brembo-equipped systems on R/T, Scat Pack, and SRT variants. To know the exact size on your car, you need the model year, trim, and ideally the VIN or a parts lookup for the precise brake package installed.

Rotor size ranges by trim (rough guide)

The following ranges give a general sense of what sizes have appeared on typical Charger configurations. Exact measurements depend on the year and option package, so use these as a reference rather than a guarantee.

Base/Value Chargers (V6 and entry trims)

• Front rotors: approximately 12.6"–13.0" (320–330 mm)


• Rear rotors: approximately 11.5"–12.1" (290–310 mm)

These sizes reflect the more modest braking setups found on standard, non-performance Chargers. For precise figures on a specific vehicle, verify against the owner's manual or a dealer parts lookup using the VIN.

R/T and Scat Pack trims

• Front rotors: approximately 14.0"–14.7" (356–374 mm)


• Rear rotors: approximately 12.6"–13.8" (320–350 mm)

R/T and Scat Pack models upgrade to larger discs to support higher performance and stopping power. Exact sizes vary by year and brake package, so check the exact specification for your car if you need a precise number.

SRT and Hellcat variants

• Front rotors: approximately 15.0"–15.4" (381–391 mm)


• Rear rotors: approximately 13.0"–13.8" (330–350 mm)

High-performance SRT/Hellcat Chargers use the largest rotors offered, often with multi-piston calipers and Brembo hardware. As with other trims, exact sizing depends on the model year and package, so confirm with a parts lookup for your specific vehicle.

How to confirm your exact rotor size

To determine the precise rotor size for your Dodge Charger, use these steps. Each car can have a unique brake package even within the same model year and trim, so checking specifically for your vehicle is the most reliable method.

1. Identify your exact model year and trim level (and any optional brake package) using your door jamb sticker or the VIN.


2. Use the VIN to pull official brake specifications from Dodge/Mopar parts catalogs or the dealer’s service portal.


3. Inspect the rotor itself: look for diameter markings stamped on the rotor surface or the rotor edge; compare to the potential size ranges for your trim.


4. Check the caliper/part numbers: brake hardware often has codes that help confirm rotor size when cross-referenced with Dodge’s catalogs.


5. When in doubt, contact a Dodge dealership or a qualified shop with the VIN to confirm the exact rotor diameter and package.

Knowing the exact rotor size is especially important for brake service, rotor replacement, or choosing compatible aftermarket components. A precise lookup ensures you don’t install the wrong diameter discs or incompatible calipers.

Summary

The Dodge Charger does not have a single rotor size. Front rotor diameters typically range from about 12.6" to 15.4" and rear rotors from about 11.5" to 13.8, depending on whether the car is a base model, an R/T/Scat Pack, or an SRT/Hellcat variant, as well as the model year. To get the exact size for your vehicle, check the VIN against official Dodge/Mopar brake specifications or consult the dealership parts desk. Always confirm with a reliable source for your specific car before servicing or replacing brakes.

What size are Dodge Charger rotors?

Detroit Axle - Brake Rotors for 2014-2023 Dodge Charger [Pursuit], 2015 2016 2017 2018 2019 2020 2021 2022 Drilled Slotted Disc Brake Rotors Replacement : 14.57" inch Front & 13.78" inch Rear Rotor.

What size socket for rotors?

The rotor is secured by the tire and wheel assembly, so you'll need a 19mm socket to remove the wheel nuts, a 14mm for the caliper bolts, and an 18mm for the caliper support. You do not need to remove the large axle nut to take off the rotor.

What size wheels are on a Dodge Charger?

Dodge Charger wheel sizes vary by model year and trim, but typically range from 17-inch to 20-inch for base models and can go up to 20-inch or larger for performance trims. Common stock sizes include 215/65R17 (SXT) and 245/45R20 (R/T, Scat Pack). Performance models like the Widebody trims often use wider tires, such as 305/35R20. Regardless of size, most Chargers use a 5x115 bolt pattern.
 

Trim Level	Common Wheel/Tire Size
SXT	215/65R17
SXT AWD	235/55R19, 245/45R20
GT	245/45R20
R/T	245/45R20
Scat Pack	245/45R20, 275/40R20
Scat Pack Widebody	305/35R20
SRT Hellcat / Hellcat Redeye Widebody	305/35R20

• For aftermarket wheels, diameters from 19 to 22 inches are popular, with widths often between 9-10 inches in the front and 9.5-11 inches in the rear, depending on the desired fitment. 
• Always check your specific model's owner's manual for the exact factory specifications. 

How do I tell what size my rotors are?

To measure a rotor's size, find its diameter by measuring across its center with a tape measure or caliper, and its thickness by using a micrometer or caliper at multiple points on the friction surface. For the most accurate measurements, remove the rotor from the vehicle first.

Measuring rotor diameter

• Method 1: Measure with the wheel removed 
  • Use a tape measure or a large caliper. 
  • Measure from one outer edge of the rotor straight across to the opposite outer edge, ensuring the measurement goes through the exact center. 
• Method 2: Measure with the wheel on
  • Use a large caliper or a method using a paper template with a hole for the hub to make an imprint on the paper, then measure the imprint. 
  • Another method is to use two magnetic markers attached to the rotor's surface and a tape measure to measure the distance between the magnets. 

Measuring rotor thickness

• Method 1: Measure with the wheel removed 
  • Use a micrometer or a caliper. 
  • Measure the thickness at several different points along the friction material of the rotor to account for wear. 
• Method 2: Measure with the wheel on
  • Use a small caliper to measure the thickness in a few spots on the rotor's surface. 

Other important measurements

• Hat height: With the rotor upside down on a flat surface, measure the distance from the base to the start of the friction material. 
• Runout: Use a dial indicator to check for runout, which is an indicator of rotor wobble.
