FAQ
Frequently Asked Questions
Got questions about compatibility, shipping, or returns? We've got answers.
How does Fatman Parts guarantee fitment?
We match your vehicle's exact year, make, model, and engine against our database of 18,000+ verified OEM fitment rules. If a part you verified with our tools doesn't fit, we will cover the return shipping and make it right immediately.
Can I use my VIN to find parts?
Yes. Entering your 17-digit VIN (Vehicle Identification Number) in our lookup tool is the most accurate way to decode your vehicle's trim, options, and engine package. This ensures you only see parts that match your exact vehicle build.
Do you sell both new and used auto parts?
Yes, we sell both brand-new and high-quality, inspected used auto parts. Each listing is clearly marked so you know the exact condition and source of the item before adding it to your cart.
Are these parts OEM or aftermarket?
We offer both original equipment manufacturer (OEM) parts and premium aftermarket replacements. Every product card is clearly badged with its condition (New/Used) and source (OEM/Aftermarket) so you can make an informed choice.
Are the product images exact representations of the parts?
No. Because we manage a massive database of fast-moving inventory coming and going daily, product images are representative. The part number listed on the product card is the exact part you will receive.
How long does processing and shipping take?
Orders are processed at our U.S. warehouses within 24 to 48 hours. Shipping typically takes 2 to 5 business days depending on your location. Standard shipping is free on orders over $99.
What is your return policy if a part doesn't fit?
We offer a 30-day return policy on all uninstalled, clean parts in their original packaging. If you used our fitment verification tools before buying and the part still does not fit, we cover the return shipping label costs 100%.
