At American Used Auto Parts LLC, quality control is the foundation of our business. Our standardized sourcing and verification process ensures mechanical integrity across all domestic and import powertrains.
We source used engine assemblies exclusively from verified insurance auctions and dismantling partners. This ensures we obtain units with a traceable VIN history, allowing us to verify the donor vehicle's mileage and status before it enters our inventory network.
Our technicians focus on the critical internal components that define the engine's lifespan.
Compression Verification: We test cylinder pressure to ensure rings and valves are sealing within OEM tolerances.
Visual Leak Check: We inspect for external block cracks, manifold damage, and excessive oil residue on the head gasket mating surfaces.
Crank Rotation: Verification that the crankshaft turns 360 degrees smoothly with no internal binding or rod knock.
Fluid Analysis: We check for "milkshake" oil (coolant mixing), which indicates head gasket failure, ensuring you never receive a compromised unit.
To provide the best value, our engines are sold as Long Block Assemblies.
Included: Block, Cylinder Heads, Pistons, Crankshaft, Camshafts.
Convenience Items: Accessories such as the Intake Manifold, Alternator, AC Compressor, and Water Pump may be left attached for your convenience, but they are not covered under warranty. We highly recommend installing new OEM accessories or swapping your original units to guarantee reliability.
Once approved, every engine is fully drained of hazardous fluids, strapped to a standard 4x4 pallet, and shrink-wrapped. This ensures your assembly arrives safe, secure, and ready for your mechanic to prep.
Don't let a mechanical failure keep your vehicle off the road. American Used Auto Parts LLC makes the sourcing process transparent and secure.

At American Used Auto Parts, we are all about getting your vehicle running great and saving you money. With our extensive inventory and commitment to quality, we are your go-to source for reliable used auto parts.
Genuine used auto parts are high-quality components reclaimed from vehicles to offer a cost-effective repair solution. We provide a wide array of inspected OEM items including engines, transmissions, alternators, rear axles, AC compressors, and other essential mechanical components, helping you restore your vehicle’s performance for less.
The most immediate benefit of choosing recycled auto parts is the substantial value compared to purchasing new dealer components. For vehicle owners managing maintenance costs, this translates into smart financial savings, allowing you to get your car back on the road efficiently without compromising on quality.
Unlike generic aftermarket copies, recycled auto components are Genuine OEM parts originally manufactured by your vehicle’s maker. This ensures precise fitment and established performance standards. To provide complete confidence, every part we sell is inspected and backed by our comprehensive warranty, offering you total peace of mind.
Choosing recycled car parts is a win for the environment. By opting for reclaimed components, you are actively participating in the circular economy, keeping usable materials out of landfills. This practice significantly reduces manufacturing waste and contributes to the conservation of natural resources.
No matter what specific assembly you are searching for, our extensive network makes it simple to find. From replacement parts for domestic trucks to imported sedans like BMW or Honda, our vast selection ensures you can easily source the exact auto part you need, shipped directly from facilities in the USA.
Our used engines are sold as a Long Block. This means you receive the engine block, cylinder heads, pistons, crankshaft, and valvetrain. External accessories such as the intake manifold, alternator, starter, AC compressor, and turbocharger may be left attached for convenience, but they are not covered under warranty. We recommend transferring your original, verified accessories to the replacement block for the best results.
Fitment is verified using your vehicle's 17-digit VIN (Vehicle Identification Number). Before we ship any order, our parts specialists cross-reference your VIN with the replacement engine's code (e.g., Ford 5.4L 3V vs. 2V, or Chevy 5.3L AFM vs. Non-AFM). This process ensures a 100% mechanical match for your specific year and model.
We can ship to both! However, engines are shipped via heavy commercial freight (18-wheeler trucks).
No. Our standard 6-Month Parts Warranty covers the replacement of the defective engine block or a refund of the purchase price. It does not cover labor costs, towing, rental cars, or fluids. We strongly recommend inspecting the engine upon arrival and replacing common wear items (water pump, timing belt/chain, rear main seal) before installation.
If you order the incorrect part or change your mind, you may return the item within 30 days, provided it has not been installed or modified. Please note that a 25% Restocking Fee will apply, and the customer is responsible for return shipping costs. This fee covers the logistics of moving heavy freight back to our warehouse.
