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 car splits in ways that are not obvious from the outside, which is why the model year matters. Alpha platform sedan that replaced the CTS, including the CT5-V Blackwing.
Old invoices are useful and also risky. A part number from a repair five years ago may have superseded twice since then. We can trace the current equivalent from the original number in a couple of minutes.
The 2020 model year is the first year of the Cadillac CT5, so parts from the previous nameplate generally do not carry over and first year production changes are common. Build date matters more than usual. Trim level changes brake sizing, wheel bearings and suspension components on these cars.
The parts we ship most for the 2020 Cadillac CT5 are window regulators, headlamp assemblies, AC compressors, front wheel bearings and control arm bushings. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction. 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.
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 2020 Cadillac 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.
