That locks in your vehicle so every part we show fits. Genuine GM parts at up to 40% off dealer prices.
The catalog for a compact crossover splits in ways that are not obvious from the outside, which is why the model year matters. Theta through 2017, D2XX from 2018 to 2024, and a new generation from 2025.
The 2017 Terrain was in the middle of its production run, so the catalog reflects incremental changes rather than a clean break. Turbocharged and naturally aspirated versions of the same crossover share very little across the front of the engine.
The parts we ship most for the 2017 GMC Terrain are window regulators, headlamp assemblies, mirror assemblies, AC compressors and wheel speed sensors. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. On a compact crossover these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
The catalog is organized by assembly group rather than by symptom, which trips people up. If you know what failed but not what it is called, give our specialists the symptom and the VIN and they will find the group it lives in.
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 2pm Central usually go out the same business day. If you are servicing more than one vehicle from that year, our 2017 GMC catalog covers the rest of the lineup.
We specialize in GM vehicles that are 10 to 15 years old, and we often carry new-in-box parts for older models too. Discontinued parts are a normal part of the OEM business. When GM stops making a part and our stock is gone, that is the end of the line for that OEM part. We thank you in advance for understanding. The GM Parts Club advantage: our massive buying power lets us stock deep on the parts GM owners need, in our huge warehouse in Dallas, Texas.
