2012 Chevrolet Colorado Catalytic Converters

Genuine GM catalytic converters for the 2012 Chevrolet Colorado, at wholesale prices. Converters are emissions parts, and the substrate loading has to match what the ECM expects from the downstream oxygen sensor. GMT355 through 2012, the 31XX mid-size from 2015 to 2022, and a new generation from 2023. There were no 2013 or 2014 model years.

When to replace

A P0420 code, rattling from underneath, or a failed emissions test. On a mid-size pickup, two trucks with the same badge can take different parts once cab style and drivetrain are accounted for.

Avoiding the wrong part

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
