ShopEarl.com is a network of American auto part suppliers - salvage yards, aftermarket vendors, and powertrain remanufacturers.

Our mission is to make finding the right auto part easy, affordable, and environmentally friendly by giving quality used parts a second life and keeping them out of landfills.

We use a comprehensive vehicle fitment database that matches parts to specific makes, models, years, and engine types.

For critical components like engines and transmissions, we also require VIN verification for your vehicle to ensure an exact match. The VIN (Vehicle Identification Number) contains specific information about your vehicle's configuration that helps identify the exact parts it needs.

If you're ever unsure about fitment, our team is available to help verify compatibility before you make a purchase.

ShopEarl.com accepts the following payment methods:

Major credit and debit cards, including Visa, MasterCard, and American Express

Affirm / Link / Apple Pay / Google Pay

All payment data is encrypted using TLS technology. We never see or store your full payment information—only a secure token provided by our processor to complete your purchase.

ShopEarl.com offers free shipping within the continental United States. Shipping times can vary depending on shipping methods, and ‘unbolted’ used parts typically ship a day faster than ‘yard’ parts that have to be professionally dismantled from the vehicle first. You’ll receive email and text notifications every step of the way.

Delivery to commercial locations is always free, but larger parts that ship freight may incur surcharges if they are delivered to a residential address. You can always ship these for free to a repair facility or our team can help find a nearby commercial address for local pickup.

At the moment, we don’t offer expedited shipping options. However, we’re always looking for ways to improve our services, and we hope to offer faster shipping options in the future.

All parts come with a minimum 30 day return window from the date your part arrives. See full return policy for all the details.

Used parts are OEM auto parts professionally dismantled by certified auto recyclers.

Remanufactured parts are used OEM parts that have been completely disassembled, cleaned, and rebuilt with new components where necessary. They're tested to meet or exceed original equipment specifications, and often come with warranties similar to new parts.

New parts are new, aftermarket components that have never been installed on a vehicle.
