Frequently Asked Questions

Can I rely on the vehicle compatibility tool to verify proper fitment?

The vehicle compatibility tool is a starting point to find lug nuts or lug bolts that are a safe and proper fitment for your vehicle. The tool can verify the correct thread size using your vehicle’s year, make, and model but it does not match the lug style to your wheel. If you need additional help verifying fitment, please give us a call or send us a message. Our Customer Experience Team and DP Fitment Specialists are here to help.

I know these will fit, but the compatibility tool says otherwise. What’s going on here?

Chances are that these will fit your vehicle and wheel application just fine, but we recommend verifying fitment with a DP Fitment Specialist before making your purchase. eBay’s compatibility tool will only allow us to add a small amount of vehicles to this product listing. For that reason, we start with newer vehicles and work our way back.

What is the difference between "Factory OE" and "Aftermarket" wheels?

Factory OE wheels are made by the vehicle's manufacturer while aftermarket wheels are made by another source. There are many different manufacturers of aftermarket wheels, but some brands include American Racing, Enkei, Helo, ION, KMC, Touren, XD, etc. The difference between factory OE and aftermarket wheels can have a huge impact on the style of lug nut or lug bolt required for your application. Refer to the listing title, bullet points, and fitment notes when verifying proper fitment. If you have any doubts, our Customer Experience Team and DP Fitment Specialists are here to assist you.
