Quick answers
Frequently asked questions
1How do I ensure I'm ordering the correct part for my vehicle?⌄
Always start by accurately selecting your vehicle's Year, Make, Model, and Engine. RockAuto's catalog is designed for specific fitment. Pay close attention to any 'Info' icons next to parts, which may provide critical details like VIN splits, production dates, or specific options that affect compatibility. Comparing the part image and description to your existing part is also recommended.
2What are the shipping options and costs?⌄
Shipping options and costs are calculated in real-time based on the items in your cart, your shipping address, and the warehouse locations of the parts. You can see estimated shipping costs before finalizing your order by entering your zip code in the cart. RockAuto often ships from multiple warehouses, which can sometimes result in separate packages and shipping charges.
3Can I return a part if it's incorrect or I no longer need it?⌄
Yes, RockAuto generally accepts returns for most parts within a specified period (typically 30 days) from the invoice date, provided they are in new, uninstalled condition and in their original packaging. You'll need to initiate a return request through their website to obtain a Return Merchandise Authorization (RMA) number and specific shipping instructions. Return shipping costs are typically the responsibility of the customer unless the return is due to a RockAuto error.
4Do you offer parts for classic or obscure vehicles?⌄
RockAuto is known for its extensive catalog, which often includes parts for a wide range of older, classic, and less common vehicles. While availability can vary, it's always worth checking their Year/Make/Model selector for your specific vehicle, as they frequently stock new old stock (NOS) or specialty aftermarket components that might be difficult to find elsewhere.
