17 Top Auto Parts Companies

What to check before you order car parts

Online parts stores carry huge catalogs, and fit is the main risk. A part that looks right can differ by engine, trim level or production date.

• Fitment. Enter your exact year, make, model and engine, and use your vehicle identification number where the store allows it. Compare the part number with your old part.
• Original, aftermarket or used. Know which you are buying. Prices and warranties differ.
• Core charges. Parts such as batteries and alternators may carry a refundable core charge, returned when you send back the old part.
• Tires. Check size, load index, speed rating and manufacture date. Ask about installation partners.
• Split shipments. Large orders may arrive in separate boxes from different warehouses.

Avoiding wrong parts and costly returns

Wrong parts, restocking fees, return shipping costs and slow refunds come up most in reviews. Do not install a part until you are sure it fits, because installed parts are often not returnable. Keep the packaging until the job is done. On CandorRated, each company page shows who appears to run the website, how long the domain has existed, the contact details found and reviews from other buyers. Filter by country or city to find a shop nearby when you need a part the same day.
