Towing Capacity of 2017 GMC Terrain with 4 Cylinder Engine
Question:
How big of a trailer can I pull
asked by: Scott W
Expert Reply:
I took a look at the online owner's manual for your 2017 GMC Terrain. It states that the 2.4L L4 Engine model Terrain has a towing capacity of 1,500 pounds for trailers with brakes and 1,000 pounds for trailers without brakes. I do recommend verifying this in your copy of the owner's manual, as its possible that you have a slightly different model.
If you do not yet have a trailer hitch installed on the vehicle, I recommend the etrailer Class III # e98865. This custom-fit, Class III hitch will use existing holes in your Terrain's frame for a no-drill installation. I have attached an installation video on your 2017 model that you can use for reference.
For trailer wiring, I recommend the Tekonsha T-One Vehicle Wiring Harness # 118494 if you do not have the factory tow package. This custom harness will install by connecting directly to built-in ports located behind the driver's-side and passenger's-side interior trim panels in the rear cargo area. Once plugged in, you will simply need to run the hot lead up to the Terrain's battery.
I have again attached an installation video that you can use for reference.
Lastly, in order to tow a trailer, you will need a ball mount and hitch ball. I have attached a great article that explains exactly how to determine the best ball mount for your application, along with a link that will take you to our available selection.
