That locks in your vehicle so every part we show fits. Genuine GM parts at up to 40% off dealer prices.
Sourcing parts for a mid-size car comes down to matching the right generation, and that is where most orders go wrong. Alpha platform rear-drive sedan that replaced the ATS, including the CT4-V Blackwing.
The parts we ship most for the 2020 Cadillac CT4 are water pumps, thermostat housings, ignition coils, timing chains and guides and window regulators. 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.
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.
The 2020 model year is the first year of the Cadillac CT4, 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.
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.
