2010 GMC Acadia Catalytic Converters

Genuine GM catalytic converters for the 2010 GMC Acadia, at wholesale prices. Converters are emissions parts, and the substrate loading has to match what the ECM expects from the downstream oxygen sensor. Lambda through 2016, C1XX from 2017 to 2023, and a larger new generation from 2024.

How you know

A P0420 code, rattling from underneath, or a failed emissions test. On a mid-size SUV, vehicles with air ride or magnetic dampers take different parts from those on the standard setup.

The case for genuine GM

• Ships from Dallas. Catalytic Converters ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on catalytic converters that did not fit.
• GM stands behind it. The catalytic converters warranty comes from the manufacturer, not from us.

Confirming fitment

When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
