What are OEM Used Auto Parts?
An OEM used part is the same component your vehicle left the factory with, removed from a donor vehicle rather than manufactured fresh. It carries the original manufacturer's part number, the original tolerances and the original fit.
That matters because aftermarket parts are built to fit several models at once, which means looser tolerances and inconsistent quality between production runs. A used vehicle parts supplier is selling you the part your car was engineered around — not an approximation of it.
The trade-off is that a used part has history. That's why every unit we handle is inspected for wear, corrosion and damage, verified against the OEM interchange number for your VIN, and — for engines — compression tested before it is approved.

Vehicle owners and DIY buyers

VIN-matched fitmentHow We Test Every Part Before It Ships
You receive the mileage, the donor vehicle details and the exact contents of your unit in writing before you pay. Engines ship as a long block — cylinder head, block and internal rotating assembly. Accessories such as the alternator, starter, intake manifold, sensors and wiring harness may or may not be included, and we confirm which in writing on your specific unit.
What the 90-Day Warranty Covers
Buying used auto parts with warranty cover is the difference between a calculated saving and a gamble. Here is exactly what ours does.
Parts only, on every eligible unit.
Covered
- Internal mechanical failure on engines — rod knock, cracked block, excessive smoking
- Internal mechanical failure on transmissions and drivetrain units
- Parts only, for 90 days from delivery, on every eligible unit
Not Covered
- Labour and installation costs
- Damage caused by improper installation or by running the unit without correct fluids
- Consequential damage to other components
How a claim works. You submit a diagnostic report, an installation report from a licensed shop, and photo or video documentation of the fault. We review and respond. Orders cancelled or returned because the wrong part was ordered may carry a 25% restocking fee. A specialist will walk you through the full terms before you buy, not after.

How to Order in Three Steps
Send Your Vehicle Details
Send your year, make, model, and part details. Include your 17-digit VIN if you have it to remove guesswork. Use the form above or call 1-800-606-1107.
We Verify and Quote
Our specialist confirms the OEM interchange match, checks stock across our recycler network, and provides the mileage, unit contents, and delivered price. Quotes are typically returned within one business hour.
We Ship Free
Once payment clears, your unit is prepared and dispatched within 3–7 business days to anywhere in the continental US.
A used four-cylinder engine typically runs $900 to $1,900, and a V6 or V8 $1,400 to $3,200, delivered.
Price depends on mileage, model year, and availability. Delivery across the continental US is included, so the quoted figure is what you pay.
We match every part using your 17-digit VIN and the OEM interchange number, not just year, make, and model.
Two identical-looking vehicles from the same model year often take different units, which is why the VIN check matters. We confirm the match in writing before you pay.
Every eligible unit carries a 90-day parts-only warranty from the date of delivery.
It covers internal mechanical failure such as rod knock, cracked blocks, and excessive smoking. It does not cover labour, installation errors, or damage from running incorrect fluids.
For most vehicles, under 100,000 miles is a comfortable range.
Between 100,000 and 150,000 miles can be workable on well-maintained platforms. We record and disclose the mileage of your specific unit in writing before you pay, so you can decide with real numbers.
It is safe when the seller has a verifiable address, a written warranty, and a documented testing process.
We operate from a physical facility in Rancho Cordova, California, and put mileage and unit contents in writing before payment.
Yes. Year, make, model, engine size, and trim are enough for us to start.
The VIN simply removes the remaining guesswork on interchange, which is why we ask for it. Without one, we will confirm the match with you before shipping.
Stop overpaying for new parts. Get a quote on tested OEM components with free delivery anywhere in the continental US.
