Genuine GM Parts for the 2012 Chevrolet Avalanche

The catalog for a light duty pickup splits in ways that are not obvious from the outside, which is why the model year matters. GMT800 for 2002-2006 and GMT900 for 2007-2013, with the midgate that folds the bulkhead into the bed.

Fitment questions account for roughly a quarter of the OEM orders we handle, and almost all of them trace back to the same cause: one vehicle, several nearly identical parts, one correct answer. The VIN resolves it every time.

For 2012 the underlying design was carried over, so the parts that split are the ones tied to options, trim and build date rather than platform. Cab style, box length, drivetrain and rear axle ratio all split the catalog on these trucks, and two trucks with the same badge on the tailgate can take different parts.

The parts we ship most for the 2012 Chevrolet Avalanche are front differential seals, intake manifold gaskets, ignition coils, front hub and bearing assemblies and upper and lower control arms. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction. On a light duty pickup 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 3pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. Parts for the 2011 Avalanche and the 2013 Avalanche are listed separately, because the differences between adjacent years are real.
