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 catalog for a mid-size pickup splits in ways that are not obvious from the outside, which is why the model year matters. Four-door pickup version of the H3, built for only two model years.

The 2010 model year is the last year of the Hummer H3T, which usually means the parts bin was stable by then. Late production runs can still carry running changes, so build date is worth checking. Extended cab and crew cab trucks differ through the body, glass and interior hardware even within the same model year.

The parts we ship most for the 2010 Hummer H3T are sway bar links, brake rotors and pads, fuel pump assemblies, window regulators and door handles. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. On a mid-size pickup these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.

Body and exterior parts are where fitment errors get expensive, because a panel that is close but not correct will not line up with the panels around it. Confirm those against the VIN before ordering rather than after.

Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back. We ship from Dallas, and in stock orders placed by 3pm Central usually go out the same business day. If you are servicing more than one vehicle from that year, our 2010 Hummer catalog covers the rest of the lineup.
