You can count on used GMC engines. You don't always have to buy a new truck or SUV when your GMC engine breaks down. A used GMC engine that has been tested and certified can bring your car's performance, reliability, and fuel efficiency back to life for thousands of dollars less than a new or remanufactured engine.


All used engines come from donor cars that have low mileage and are thoroughly tested and inspected to make sure they meet OEM performance standards. A good used engine gives you factory-level power and reliable performance for a lot less money than a new one. This is true whether you drive a GMC Sierra, Yukon, Acadia, Terrain, Canyon, or Savana.


What sets a premium used GMC engine apart?

A reliable used engine is more than just a part that has been salvaged. We carefully check, test, and get ready every used GMC engine for installation to make sure it will last for a long time.

Every unit goes through:

Testing for leaks and compression

Check the oil pressure and cooling system

Check the mileage and VIN

Check the cylinder head and block

Checking oil and coolant for contamination

Cleaning and packing done by professionals

We only send our customers the best engines because we don't accept any that don't meet strict OEM performance standards.

You can see everything and be sure before the installation starts.


Works with all GMC models

We have used engines that have been tested and certified for almost every GMC model made between 2000 and 2024, including:


  • GMC Sierra 1500, 2500, and 3500 
  • Yukon, Yukon XL, and Denali 
  • GMC Acadia
  • GMC Terrain 
  • GMC Canyon
  • GMC Savana Van 
  • GMC Envoy Jim

Giving your VIN guarantees that the part will fit perfectly with your engine code, year, and drivetrain setup.


Benefits of Cost

Used GMC engines can save you 50% to 70% compared to new OEM engines. Installation is quick, easy, and cheap because they have been tested and verified by VIN.


Average prices for each model:

GMC Sierra 5.3L V8: $2,500 to $4,200 Yukon 6.2L V8: $3,200 to $4,800

GMC Terrain 2.4L: $1,800–$2,900

GMC $2,400 to $3,800 for Acadia 3.6L

The price range for the GMC Canyon 3.6L is $2,300 to $3,600.

A verified used GMC engine can bring your truck or SUV's performance and value back up without the cost of a dealership replacement.


Help with shipping and installation

All used engines are carefully put on pallets and wrapped in shrink wrap to keep them safe during shipping. We deliver all over the country, and for both homes and businesses, you can choose to have a liftgate service.

Delivery usually takes 3 to 7 business days.

We can also suggest certified installation partners who work in your area. Every engine shipment comes with instructions for installation and registering the warranty.


"A used GMC engine that has been tested and certified will give your truck back the power and dependability it needs without the cost of buying a new one."


When is it time to get a new GMC engine?

It's usually better to replace the engine than to keep fixing one that keeps breaking. You might need a new one if you see:


  • Knocking in the engine or noise from metal hitting metal
  • A lot of oil use or loss of compression
  • Too much heat or dirty coolant
  • Failure of the bearing or a knock in the rod
  • Failure of the head gasket
  • Total engine lockup

Putting in a used engine saves time and money while bringing back reliable performance.


A choice that is good for the environment and lasts

It is good for the environment to choose a used GMC engine. Reusing OEM engines cuts down on emissions from factories, saves raw materials, and cuts down on waste. This lets you drive in a way that is good for the environment without sacrificing performance.

Notes that sit next to the quote

After replacing the GMC engine, take care of it.

Follow these tips for taking care of your used engine after installation to make it last longer:

After the first 500 to 1,000 miles, change the oil and filter.

Use the fluids that the factory says to use

Check the levels of oil and coolant on a regular basis.

Don't tow or drive at high RPMs during the break-in period.

Follow the maintenance instructions in the warranty.

A used GMC engine that is well cared for can run like new for a long time.
