What Should I Know About Genuine Mopar Alternator Fitment?

When you're picking out a Mopar alternator for sale, it must fit your CDJR model in several ways for proper operation and safety. First, the alternator must have the correct amperage rating for your automobile. These numbers will vary by iteration and year. For instance, a Ram 2500 heavy-duty truck typically requires a higher-output alternator than the light-duty Ram 1500 to support its more rigorous commercial demands.

Your chosen alternator should also match the physical casing of the one inside your vehicle's engine bay. For example, if you're buying an OEM Dodge alternator for your Charger, it should be the exact case size and have the same mounting holes and pulley alignment as the configuration on your current car.

You can learn more about your vehicle's specific requirements by checking your VIN or year, make, and model in our parts finder tool.

What Parts Should Be Inspected When Replacing a Mopar Alternator?

Whether you're installing an OEM Jeep alternator or one for a Chrysler variant, it's wise to check the following parts as you do so:

Car battery and terminals
Serpentine belt
Belt tensioner
Main charging cable (the B+ wire)

It's best to test your battery's health, as a weak one can make your Mopar replacement alternator work too hard or potentially fail. Checking the serpentine belt for cracks or fraying and the belt tensioner for proper spring tension are also important to ensure your new alternator generates and maintains high output.

One of the easiest ways to find the right alternator for your car is to enter your VIN or make, model, and year into our parts finder. This will allow us to ensure that we get the right Mopar replacement alternator for your automobile, whether you need an OEM Chrysler alternator or one for a Jeep SUV.

Do Ram trucks need a different alternator than Jeep or Dodge vehicles?
