The catalog for a mid-size car splits in ways that are not obvious from the outside, which is why the model year matters. Second generation Sigma through 2013 and the Alpha based third generation from 2014 to 2019.
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 A part number from a repair five years ago may have superseded twice since then.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 2013 CTS was in the middle of its production run, so the catalog reflects incremental changes rather than a clean break. Trim level changes brake sizing, wheel bearings and suspension components on these cars.
The parts we ship most for the 2013 Cadillac CTS are brake rotors and pads, water pumps, thermostat housings, ignition coils and timing chains and guides. 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.
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 3pm Central usually go out the same business day. Parts for the 2012 CTS and the 2014 CTS are listed separately, because the differences between adjacent years are real.
