Rock Auto

Rock Auto

Rock Auto is an online retailer that specializes in aftermarket car parts. The company was founded in 1999 by two engineers who were frustrated by the limited selection and high prices of auto parts at brick-and-mortar stores. Rock Auto has since grown into one of the largest online retailers of aftermarket car parts, offering millions of parts from over 300 manufacturers.

One of Rock Auto’s biggest advantages is its competitive pricing. The company offers low prices on many of its products, and they also offer a variety of promotions and discounts throughout the year. In addition, Rock Auto has a user-friendly website that makes it easy to find the parts you need, and they offer fast and reliable shipping.

Consumers who shop on Rock Auto may have concerns about the quality and authenticity of the parts they are purchasing. While Rock Auto does offer parts from reputable manufacturers, they also offer parts from lesser-known brands that may not meet the same quality standards. Consumers should always do their research and read reviews before making a purchase on Rock Auto to ensure they are getting a reliable product. Additionally, consumers should pay attention to shipping costs and delivery times, as Rock Auto’s shipping fees can vary depending on the size and weight of the parts being ordered.

Parts Geek

Rock Auto

On the other hand, Parts Geek is a discount parts retailer that offers tons of OEM and aftermarket parts for various makes and models, specializing in hard-to-find parts at affordable prices. However, they have questionable customer service policies, such as requiring customers to ship back the wrong or missing parts at their own expense without reimbursing them for shipping costs. This can be a challenge for customers who expect excellent customer service from other retailers such as Amazon.

Despite their customer service policies, Parts Geek remains one of the most affordable parts retailers in the market, offering free shipping on all orders. Their easy-to-use vehicle selector helps ensure that the parts customers purchase will fit their specific vehicle. Therefore, if you’re looking for a way to save a few bucks on auto parts, Parts Geek is a great choice, as long as you double-check your part numbers.

OEM stands for Original Equipment Manufacturer, which means the parts are made by the same company that makes the vehicle. Meanwhile, aftermarket parts are produced by a different parts company and are often designed to be compatible with as many makes and/or models as possible.

Should I Buy OEM or Aftermarket?

Because they are made in the same way as genuine parts, OEM parts tend to be more reliable than aftermarket parts and last for longer. Warranty. OEM parts should come with a warranty to protect you if the part is defective or doesn’t work properly. The specific warranty will differ by manufacturer.

Is It Worth Buying Aftermarket Car Parts?

The main benefit of an aftermarket part is lower cost. Cost can vary somewhat between brand, although you can always expect some savings in comparison with OEM. Lower cost doesn’t always equal lower quality, either.
