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 mid-size SUV splits in ways that are not obvious from the outside, which is why the model year matters. Lambda through 2016, C1XX from 2017 to 2023, and a larger new generation from 2024.
The parts we ship most for the 2021 GMC Acadia are wheel speed sensors, power steering components, front hub and bearing assemblies, control arm bushings and sway bar end links. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction. 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.
Where geography matters is landed cost. A heavy part quoted a few dollars cheaper by an East Coast seller often costs more delivered to the middle of the country than the same part shipped out of Dallas. Compare the total, not the sticker.
For 2021 the underlying design was carried over, so the parts that split are the ones tied to options, trim and build date rather than platform. Front-drive and all-wheel-drive versions differ through the rear suspension, exhaust and underbody.
Send us your VIN before you order and our parts specialists will confirm the exact part number for your vehicle. Orders placed by 2pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. If you are servicing more than one vehicle from that year, our 2021 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.
