As I was driving to work a couple of weeks ago, my speedometer stopped working, and the radio display went black. But I switched off the headlights, and these accessories bounced back to action. It was a problem with my alternator. I had to consider replacing the alternator to avoid the issue from reoccurring.
Another obstacle was to choose between ultima and duralast alternators. These aftermarket alternators have some close similarities in terms of function, warranties, and price.
So, what is the main difference between ultima and duralast alternators? In short, the Ultima alternator is a product of O’Reilly, while duralast alternator is a product of Autozone. The brand difference can help you make an informed decision.
Keep reading this guide for detailed insights about the difference between ultima and duralast alternators. You’ll also learn the advantages and disadvantages associated with each alternator before making any purchase.
Differences between Ultima and Duralast Alternators
O’Reilly is responsible for manufacturing ultima alternators. The brand is highly recognizable due to its best customer service experience. Duralast alternators are products of the Autozone brand. But it is less reputable in terms of customer service experience. If you plan to mount your alternator at home, consider a brand with a better customer service experience. O’Reilly brand offers ultimate customer support during the installation process.
Ultima specializes in remanufacturing alternators and starters only. The specialization enhances the production of reliable alternators that pass all the factory tests. Duralast is an umbrella corporation that remanufactures a bunch of products. The diversity results in the production of alternators that ends up failing some tests. Consider alternators with a name rebuilder to enjoy years of reliability. I recommend the ultima alternator over the duralast alternator under this category.
Durability and Longevity
The average lifespan of an ultima alternator is about 100,000 to 150,000 miles. Thanks to its high-quality materials that tolerate the extreme operating conditions for an extended period. Duralast alternator has an average lifespan of about 80,000 to 130,000 miles. Some of the materials used cannot tolerate extreme conditions.
If you plan to mount an alternator that can serve you for more than seven years, consider the one with premium materials. Ultima alternator is a winner under this category.
Ultima uses the most technologically advanced processes to remanufacture high-quality alternators. The purpose is to ensure the alternator offers premium services. Duralast undertakes vigorous tests before releasing remanufactured alternators in the market.
These tests and advanced technological production ensures high-quality performance. Both duralast and ultima alternators offer premium performance. Choose any alternator from the brands since they are both winners under this category.
