This used OEM 2010–2013 GMC Sierra 1500 4.8L L20 engine for sale has 55,867 miles and was sourced from a compatible 2012 GMC Sierra L20 engine before being inspected and prepared for inventory. This VIN A engine provides a factory-spec option for buyers searching for a GMC L20 4.8L engine replacement rather than an unverified remanufactured or aftermarket assembly.

Sourced from a compatible GMC donor vehicle
Stored indoors under protected conditions after removal
Exterior block, cylinder-head areas, and mounting points visually inspected
Verified as a used OEM 4.8L L20 V8 for the listed Sierra application

This engine fits select 2010, 2011, 2012, and 2013 GMC Sierra 1500 models equipped with the 4.8L L20 V8 engine and VIN A in the 8th position. Because Sierra engine compatibility can depend on the complete VIN, drivetrain, transmission, emissions equipment, wiring, sensors, accessories, and original vehicle configuration, these details should be confirmed before installation. Interchange number 300-05648 should also be matched with the existing engine before purchase.

Before listing, this used GMC engine was inspected to assess its overall mechanical and visible condition.

Compression checked for consistency across all eight cylinders
Oil and coolant leak areas inspected around major seals and gasket surfaces
Starting and idle conditions were reviewed during evaluation
No abnormal knocking or internal engine noise noted
Exterior block and mounting areas checked for visible damage

This VIN A L20 engine includes a 6-month standard warranty, with extended warranty options available up to 1 year on eligible parts. Confirm the complete VIN, L20 engine identification, drivetrain, transmission, emissions configuration, and interchange number before ordering so the engine can be matched correctly to your GMC Sierra 1500.

OEM Used Engines

What is the difference between a remanufactured engine and a used engine?

An OEM used engine is the original factory-built engine pulled from a low-mileage donor vehicle. A remanufactured engine is disassembled, cleaned, and rebuilt, often with aftermarket parts. OEM engines retain original factory tolerances and are preferred by most mechanics. Blue Prism sells used OEM engines and transmissions, not remanufactured or aftermarket units.

Can you ship to any location in the USA?

Yes, we have a nationwide network, allowing us to ship OEM-used engines and used transmissions to any location across the United States, including major cities like Los Angeles, New York, and Chicago.

Do you also sell used transmissions as well as engines?

Yes. We also sell used OEM transmissions for all major makes and models, including Chevrolet, Ford, Honda, Toyota, Dodge, Jeep, and more. Every used transmission is an OEM-sourced unit from a low-mileage donor vehicle, tested by ASE-certified mechanics, and backed by a 1-year warranty.

Do your engines and transmissions come with a warranty?

Yes, every engine and transmission comes with warranty options up to 1 year, which applies to a major internal mechanical failure.

How long does shipping usually take?

Most engines and transmissions ship within 1–3 business days of your order. Delivery takes 2–5 business days depending on location. Customers in Phoenix, AZ, and California typically receive parts within 1-3 days. We ship to all 48 contiguous states via freight carrier.

How do I know if the engine or transmission fits my vehicle?

The most reliable way to confirm fitment is by using your vehicle’s VIN. This allows for precise matching based on your exact configuration. You can submit your details through the website or just call us at (430)-413-4976. We'll confirm the right part for your vehicle before you spend a dollar.

Are used engines and transmissions are tested before shipping?

Yes. Every part is inspected by ASE-certified mechanics before it ships. We run compression tests, check for leaks, and document the condition. If a part does not pass inspection, it does not ship.
