Limited availability on Hummer parts. GM ended the original Hummer line in 2010, so factory parts for these vehicles are getting harder to source every year. We can still get many of them through GM remaining stock and vintage parts channels, but supply is limited and availability changes without notice. If your part shows in the catalog, order it and we will confirm availability right away, or contact us first and we will check before you buy.

The Hummer H2 ran from 2003 through 2009. GMT820 built on a modified 2500 series truck frame with the 6.0L and later 6.2L V8. Because that run covers more than one engineering generation in most cases, the single most important thing you can do before ordering is confirm which year you are working on. Parts that look interchangeable across a nameplate very often are not.

Second and third row seat configuration, rear HVAC and towing package all change part numbers on these SUVs. Everything on this page is a factory GM part, built to the original specification and carrying the original part number.

The parts we move most on the Hummer H2 are water pumps, transfer case components, AC compressors, rear HVAC lines and front hub and bearing assemblies. On a full-size SUV these are the components where the difference between a factory part and a discount replacement shows up fastest, because they carry load, heat or both. If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out.

In stock orders placed by 3pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. If you are working on something else in the lineup, our full Hummer catalog covers the full catalog.
