Ordering 2018 Buick Regal Sportback parts the right way
Know your generation

Getting parts right on a mid-size car starts with knowing which generation you are working on. Liftback body style of the final generation Regal.

What we ship most for it

The parts we ship most for the 2018 Buick Regal Sportback are timing chains and guides, window regulators, headlamp assemblies, AC compressors and front wheel bearings. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. On a mid-size car these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.

Ordering tips

Fitment questions account for roughly a quarter of the OEM orders we handle, and almost all of them trace back to the same cause: one vehicle, several nearly identical parts, one correct answer. The VIN resolves it every time.

About this model year

The 2018 model year is the first year of the Buick Regal Sportback, so parts from the previous nameplate generally do not carry over and first year production changes are common. Build date matters more than usual. Engine option is the main catalog split on these sedans, and it runs through the cooling system, exhaust and accessory drive.

Fast shipping from Dallas

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. Cross-shopping a related truck? The 2018 Buick Enclave is the closest thing in the lineup that year.

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.
