Looking for reliable used auto parts without paying dealership prices? At Premium Used Auto Parts, we provide quality OEM used engines, transmissions, and other replacement components that are carefully inspected, tested, and VIN-verified for your vehicle. Every order is backed by strict quality checks, helping you get back on the road with confidence while saving significantly compared to buying new.



You can buy high-quality OEM used auto parts online from a trusted supplier offering tested parts with free nationwide shipping for all vehicle types.
Delivery anywhere in the continental US is built into the quoted price, including engines and transmissions that ship on a pallet. There is no separate delivery line, no fuel surcharge and no liftgate fee on residential deliveries. We do not ship to Alaska, Hawaii or outside the United States.
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.
Trade pricing, VIN-verified sourcing and a named specialist who answers the phone. If a unit is not in stock we source it through our recycler network rather than sending you elsewhere.
Repeat sourcing on the same platforms, consolidated delivery and priority handling on downtime-critical units.
If you are buying one engine once in your life, we will walk you through what a long block includes, what your mechanic will need, and what the warranty does and does not cover — before you pay.
We supply OEM used auto parts for all major car brands in the USA, ensuring compatibility and performance for your vehicle.
Quality used auto parts are defined by what gets rejected, not by what gets listed. Five stages, every unit, no exceptions.
The unit is checked for surface damage, corrosion, cracked castings and missing components. Anything failing here is scrapped, not discounted.
We match the OEM interchange number against your 17-digit VIN, not just year, make and model — because two identical-looking vehicles from the same year frequently take different units.
Engines are compression tested across all cylinders. Transmissions are checked for internal damage and fluid condition.
A specialist signs off against our condition standard. Mileage is recorded and disclosed to you in writing before purchase.
The unit is drained where required, cleaned, palletised and strapped for transit.
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.
Buying used auto parts with warranty cover is the difference between a calculated saving and a gamble. Here is exactly what ours does.
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.
