The Business
What you can expect
- Verified fitment before shipping
- Warranty-backed parts
- Transparent pricing
- Support throughout the process
- No shipment without your approval
Every order follows the same process. We locate the part, confirm it is compatible with your specific vehicle, share the price and mileage with you, and wait for your approval before anything ships. You are not charged a core fee. You do not need to return your existing unit. There are no deposits and no hidden fees. If a part does not meet your approval, it does not ship.
We operate as a sourcing and verification network, not a traditional junkyard. Our role is to find the right used OEM part for your vehicle, confirm it meets our quality standards and handle the process from inquiry to delivery. What you receive is a tested, warranty-backed unit that has been matched to your vehicle before it leaves the network.
Nationwide inventory, faster sourcing
Access to a network this size means we can locate compatible, quality used OEM auto parts faster and more precisely than a single local salvage yard. When a salvage yard near you does not have the right unit, we find it elsewhere. When the first option does not meet our Grade A standard, we locate another. You are not limited by what one location happens to have available on the day you call. This is what nationwide sourcing actually means in practice, and it is the core reason customers come to us to buy used OEM auto parts online rather than searching salvage yard by salvage yard.

About
What we actually do
We Source Used Auto Parts From Low-Mileage Vehicles
We Verify Quality And Compatibility Before Shipping
Sourcing the part is only the first step. Before anything is presented to you, we verify that the used OEM car part, such as a used engine or transmission, matches your specific vehicle, year, make and model. Engines are compression-tested to verify proper PSI readings and checked for leaks, knocks and smoke. Transmissions are tested for smooth gear shifting and inspected for leaks. This inspection and verification process applies to every used auto part we source. A part that passes sourcing but fails inspection does not ship. This is not a policy we added later. It is how we have operated for over 10 years in used automobile parts sales.We Match The Right Part Through Our Nationwide Network
A single local salvage yard can only offer what is physically on its lot on the day you call. When you source used OEM automobile parts through Precision Parts Pro, you are not limited by geography. Our network spans the country, which means we can locate compatible used engines or transmissions for sale that a local salvage yard simply may not have. More options mean a better match for your specific vehicle, at a more competitive price.As a result, you get a compatible, tested, used OEM car part for your vehicle without the guesswork, without the core charges and without the back-and-forth of calling salvage yard after salvage yard.
You tell us your vehicle details. We find a compatible, tested part for you.
Where our parts come from
Every part we supply comes from a vehicle sourced at a state-licensed auto auction. When the vehicle arrives, it goes through our full inspection process. When you place an order, we re-inspect the unit a second time before it ships. Two inspections on every unit, not one.
Precision Parts Pro sources used OEM automobile parts from a curated network of verified auto recyclers and suppliers across the United States. Every supplier in our network is evaluated against our sourcing standards before we work with them. We do not pull from unverified or unknown sources.
When you submit your vehicle details, we search this network specifically for your year, make and model. We are not presenting you with whatever is available.
We are locating what is compatible, confirming it meets our Grade A standard and bringing the right option to you. Over 50,000 used OEM parts for vehicles have been sourced and shipped through this process.
The reason we operate this way is straightforward. A part that does not fit costs you time and money. A part that fails costs you more. Our sourcing process exists to prevent both.

How we ensure quality
Trusted Auto Parts for Performance, Reliability, and Value.
Every used OEM part that ships through Precision Parts Pro has gone through a structured inspection process. Grade A is not a label we apply loosely. It is the result of a defined set of checks that every unit must pass before we approve it for shipment.
Our engine grading system: We classify engines into four grades: A, B, C and X. We source and supply Grade A exclusively.
A Grade A engine meets one of the following mileage criteria:
- 60,000 miles or less, or
- Between 60,000 and 150,000 miles, with no more than 15,000 miles of use per year
Every Grade A engine passes a full inspection checklist:
- Compression tested to verify proper PSI readings across cylinders
- Checked for oil and fluid leaks, engine knocking and excessive smoke
- Crankshaft manually rotated 360 degrees to confirm smooth operation
- Pistons and bearings inspected for cracks or wear
- Spark plugs and fluid conditions examined
- Visual assessment for structural damage or defects
- Inspected and approved by ASE-certified mechanics
For used transmissions:
- Gear shifting tested for smooth operation
- Leak inspection completed
- Functional performance verified
- Inspected by ASE-certified mechanics
Double inspection process: Every vehicle is inspected on arrival. When you place an order, the unit is re-inspected a second time before it ships. Two inspections on every unit, not one.
Units that do not meet these standards are not shipped. There are no exceptions. Every unit that ships carries a minimum 90-day warranty, with coverage extending up to one year depending on the unit. The quality process is not something we do because it sounds good on a page. It is why over 10,000 customers have trusted Precision Parts Pro to source used automobile parts for their vehicles.
