The ATK DCT12 is a remanufactured long block engine, fully disassembled, machined, and rebuilt with new wear parts to restore performance. This engine is constructed with aluminum cylinder heads and comes fully assembled, ready for installation. It is designed for Chevrolet and GMC vehicles equipped with the 6.0L V8 engine, specifically for the 2007, 2008, and 2009 model years. Key specifications include a 6.0L displacement, aluminum cylinder heads, and assembly completion. An intake manifold is not included with this engine. The ATK DCT12 comes with a 4-year warranty for added peace of mind. This engine is a direct fit for a range of Chevrolet and GMC vehicles, including the Chevrolet Silverado 1500 and Chevrolet Suburban 1500, as well as GMC Sierra 1500 models from the 2007-2008 model years. It is also noted as fitting Corvette and Trailblazer models with the 6.0L V8. The remanufacturing process ensures that critical components like the heads, blocks, cranks, and cams are machined and wear parts are replaced, providing a reliable replacement for your vehicle's original engine.
