OEM H3 Parts from NewGMParts.com

General Motors introduced the Hummer H3 as a mid-sized SUV. Since you like your H3, you take great care of it so that it continues to perform like new. You do all the regular maintenance, and you use genuine GM replacement parts in order to get factory performance from it.

  • Engine - In order to keep the engine performing, you take care to do the oil and filter changes, but you also know that you may need to change out valves, head gaskets and other parts that wear out over time. Whether you need to replace a crankshaft gear or an air filter element, we have the part you need.
  • HVAC - If your air is not blowing cool, you may need to replace a condenser or have a plugged line. No matter whether it is a big or small repair, we have the part that is the right fit for your H3. We carry lines, actuators, floor ducts, evaporator cores, expansion valves and the harnesses.
  • Emissions - Your emission system is instrumental in the right fuel to air mixture in your engine. If a sensor is not working, you need to replace it. We have oxygen sensors, MAP sensors, vapor canisters and the brackets to hold it and more.

We offer the entire GM catalog of new, original parts, and we also represent more than 300 specialty aftermarket parts manufacturers. In addition, we will ship all parts, even those deemed “hazardous” (such as airbags and seatbelt pre tensioners.) Order your new Hummer H3 parts today.
