Can I Use Aftermarket Parts On My Semi Truck?

When it comes to semi truck repair tips and tricks, the majority of truck owners don’t know whether they have the capacity for handling a big rig breakdown owing to some misconceptions that have been in the industry for many years. There are some vast myths associated with aftermarket parts, some of which have been highlighted below.

1. All Parts Are Created Equal

This is not the case because all aftermarket parts are not created the same. There exist significant variations when it comes to quality. When purchasing an aftermarket part, you should consider its price and whether a warranty backs it. If a part is cheaper than its OEM counterpart, it’s likely lower quality.

2. OEM Parts Are Always Better

OEM parts are sometimes but not always better than aftermarket parts. Aftermarket parts are often just as good as OEM parts, and in some cases, they’re even better. The main difference is that aftermarket parts are usually much cheaper than OEM parts.

3. Aftermarket Parts Will Void My Warranty

The issue of warranty is a bit complicated when it comes to semi-trucks. In most cases, aftermarket parts will not void your warranty. However, if you install an aftermarket part and it causes damage to your truck, the dealership may try to void your warranty. Therefore, it’s essential to read your contract carefully and understand what is not covered.

4. Price Matters Most

When purchasing aftermarket parts, the price is not always the most crucial factor. In some cases, it’s worth paying a bit more for a higher-quality part. After all, you don’t want to have to replace the part again in a few months because it’s poor quality.

5. Age of the Vehicle Matters

It is essential to consider the age of your vehicle when deciding whether to install aftermarket parts. If your truck is several years old, it’s probably not worth investing in aftermarket parts because the truck will likely need to be replaced soon. However, if your truck is new, it might be worth installing aftermarket parts to save money in the long run.

6. Brand Name Is Important

The brand name isn’t as important as the quality of the product. Many aftermarket parts manufacturers make high-quality parts. Therefore, don’t feel like you have to purchase a part from a well-known brand name to get a good product. There are little-known brands that make excellent aftermarket parts.

7. Cheap Parts Save You Money

There is a tendency for some truckers to believe that all aftermarket parts are cheap. However, this is not always the case. While aftermarket parts are often more inexpensive than OEM parts, they’re not always the most affordable option. In some cases, it’s cheaper to purchase a used OEM part than a new aftermarket part.

8. You Get What You Pay For

Generally speaking, this is true. However, as mentioned above, there are some exceptions. In some cases, you can find a high-quality aftermarket part for a fraction of the price of an OEM part. Therefore, it’s important to compare prices and read reviews before purchasing.


Aftermarket parts can be an excellent option for semi-truck owners. However, it’s essential to do your research and understand the pros and cons of aftermarket parts before making a purchase. With some knowledge, you can find high-quality aftermarket parts that will save you money and keep your truck running like new.
