GMC builds trucks and SUVs that handle serious work and daily driving without compromise. When the engine in your Sierra, Yukon, or Canyon fails, the repair bill from a dealership can stop you cold. Sourcing a used GMC engine for sale from Moon Auto Parts puts a quality tested low-mileage unit in your vehicle at a fraction of that cost.
Not every engine replacement situation calls for the same solution. A low-mileage engine pulled from a collision-damaged donor vehicle gives you original OEM internals at the lowest possible price point. A rebuilt GMC engine replaces specific worn components while keeping the original block and core intact. A remanufactured engine takes the process further by machining every internal component back to original factory tolerances with all-new pistons, rings, bearings, and seals throughout.
Moon Auto Parts carries all three types across every major GMC platform. Every unit goes through a full compression-tested GMC engine inspection and VIN-matched GMC engine fitment verification before it ships. You receive the right engine for your exact vehicle every time.
The GMC Sierra is one of the best-selling trucks in America, and its engine replacement demand reflects that. Buyers searching for a used GMC Sierra engine most commonly need the 5.3L EcoTec3 V8. The standard powerplant across Sierra 1500 WT, SLE, and SLT trims. The GMC Sierra 5.3 engine for sale produces 355 horsepower and delivers the combination of towing capability and fuel economy that made it the default choice for millions of truck buyers. The GMC Sierra 1500 engine also comes in a 4.3L V6 for earlier trims, and the high-output GMC 6.2L engine is for Denali and AT4 applications, producing 420 horsepower. Every used Sierra engine in our inventory carries documented mileage and passes our full inspection checklist before listing.
The Yukon and Yukon XL share their engine family with the Sierra. Buyers looking for a GMC Yukon engine for sale typically need the 5.3L EcoTec3 V8 or the 6.2L V8 found in Yukon Denali trims. The GMC Vortec 5300, the older generation 5.3 L used in Yukons from 1999 through 2013, is also available for earlier model owners. Both generations are stocked as OEM GMC engine units sourced from verified low-mileage donors.
The Canyon midsize pickup uses either the GMC 2.5L EcoTec engine, producing 200 horsepower, or the GMC 3.6L V6 engine, producing 308 horsepower, depending on the trim. Buyers searching for a used GMC Canyon engine will find both options in our inventory as grade-A tested units. The 2.5L is the most affordable replacement in our GMC lineup and suits Canyon owners looking for a reliable workhorse fix at a budget-friendly price.
The Acadia uses the 2.5L inline-4 and 3.6L V6 across its trim range. Buyers needing a GMC Acadia engine replacement have both options available with VIN-based fitment verification included on every order. The Terrain runs a 1.5L or 2.0L turbocharged inline-4, depending on the generation. A GMC Terrain engine for sale from Moon Auto Parts ships fully inspected with mileage confirmed against the donor vehicle title.
The used GMC Duramax engine covers Sierra 2500 and Sierra 3500 heavy-duty applications. The 6.6 Duramax engine produces up to 445 horsepower and 910 lb-ft of torque in its latest form, making it one of the most capable diesel truck engines in production. Earlier LB7, LLY, LBZ, LMM, and LML generations are also available for older Sierra HD and Savana owners. The GMC Savana engine lineup spans the 4.3 L V6 and 6.0 L V8, both stocked as tested used units for commercial fleet operators who depend on the Savana for daily work.
A GMC engine swap only makes sense when the replacement unit is cleaner and more reliable than what failed. Moon Auto Parts sources engines from over 5000 verified salvage yards across the United States and prioritises units from accident-damaged donors where the engine compartment was not involved in the impact. Technicians run a compression test on every cylinder scan for OBD-II fault codes, check oil condition for contamination, and physically inspect the block and head before any listing goes live.
Every GMC engine with a warranty we sell ships with our full 4-year / 40000-mile coverage at no extra cost. Free shipping on GMC engine orders goes to all commercial addresses nationwide. Use the search tool above to find your exact match or call our team at (888) 777-0769 Monday through Friday, 9 AM to 7 PM CST.
