Hummer built some of the most rugged, purpose-driven vehicles ever to hit American roads from the military-grade H1 to the more mainstream H2 and H3. When one of these powertrains fails, replacing it doesn't have to cost a fortune. Finding quality Hummer engines for sale is the most practical way to restore your vehicle's performance without paying new dealership prices. At Moon Auto Parts, we source every engine from verified suppliers. We inspect each one individually and back it with a 4-year warranty before it ships to your door.
Hummer launched as an American pickup in 1992 with the M998 Humvee. The brand ran until 2010, when production stopped. GMC later revived it in 2020. General Motors acquired the brand in 1998 and marketed three vehicles: the H1, H2, and H3. These models used engines including the LQ4, LQ9, LS2, and L96.
The H2 is a full-size off-road SUV that AM General built under contract from General Motors. Production ran from 2002 to 2009. Engineers based it on a modified GMT820 GM three-quarter-ton pickup truck. The H2 runs on either a 6.2L LQ4 V8 or a 6.2L L92 V8 engine.
The H3 is an off-road vehicle that GM produced from 2005 to 2010. It comes as a 5-door SUV or a 4-door pickup truck called the H3T. Unlike the H1 and H2, AM General did not develop the H3. Its base engine is a 3.7-liter LLR inline-five producing 242 hp and 242 lb-ft of torque.
The H3 also used a 3.5L L52 I5 and a 5.3L LH8 V8. Since GM halted production in 2010, these reliable and tested hummer engines for sale have become increasingly scarce. Many customers now search specifically for 2006 Hummer H3 engines and 2007 engines.
