Ordering 2020 GMC Acadia parts the right way
Know your generation

If you are keeping a mid-size SUV on the road, the fastest way to get the right part the first time is to start from the exact model year. Lambda through 2016, C1XX from 2017 to 2023, and a larger new generation from 2024.

Genuine GM, factory part numbers

Warranty is the quiet argument for factory parts. A genuine GM component carries GM's coverage, and on anything that touches the powertrain or the emissions system that coverage is worth more than the price difference on the invoice.

About this model year

2020 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. Drivetrain and trim change suspension, brake and body hardware on these crossovers within a single model year.

What we ship most for it

The parts we ship most for the 2020 GMC Acadia are liftgate struts, window regulators, headlamp assemblies, mirror assemblies and AC compressors. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a mid-size SUV these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.

Not sure it fits? Send us your VIN

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 2pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. Parts for the 2019 Acadia and the 2021 Acadia are listed separately, because the differences between adjacent years are real.

A note on older GM parts

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.
