Frequently Asked Questions: Aftermarket Auto Parts Explained

1. What are aftermarket car parts, and are they reliable?




2. Will aftermarket ball joints fit my vehicle?


3. What's the difference between OEM and aftermarket wheel hubs?



4. Do I need to replace my exhaust manifold with an OEM part?



5. Where can I buy trusted aftermarket parts online?

Aftermarket parts are components made by third-party manufacturers rather than the original equipment manufacturer (OEM). Many aftermarket parts meet or exceed OEM standards and offer great reliability when purchased from trusted brands. They're often used for both performance upgrades and everyday repairs.

Yes — aftermarket ball joints are designed to match OEM specs and fit most makes and models. Always use a vehicle selector or compatibility tool to ensure proper fitment before purchasing.

Wheel hubs from aftermarket brands often offer similar quality at a lower cost than OEM versions. As long as you choose reputable manufacturers, aftermarket wheel hubs can be just as reliable and are commonly used for suspension maintenance or upgrades.

Not necessarily. A high-quality aftermarket exhaust manifold can provide equal or better performance than OEM, especially if you're aiming for improved airflow or engine tuning. They’re also a great option when repairing cracked or worn factory manifolds.

You can find reliable, OEM-quality aftermarket car parts at AutoNation Parts — including suspension components, engine and drivetrain parts, braking systems, and more. Every part is backed by expert support and fast shipping.
