Our Story
Built in Detroit. Trusted Nationwide.
SwapMyParts started with a simple idea — recycled OEM powertrains should be as dependable as buying new, at a fraction of the cost. We source from insurance auctions and certified recyclers, then inspect every unit before it reaches our catalog.
Today we serve professional mechanics, collision shops, fleet operators, and DIY builders who need the right engine or transmission shipped fast, with honest grading and people who pick up the phone.
- Grade A / B / C ratings with verified mileage on every listing
