2007-2014 General Motors GMT900 Platform Trucks and SUVs.

To try and reduce the clutter I'm creating on the forum, I will keep all GMT900 product information contained to this thread.

2007: First year for all-new Tahoe, Suburban, Yukon/XL/Denali, Escalade/ESV/EXT, Avalanche, Silverado and Sierra.

SUVs(and Avalanche):

LS (note: black door handles and mirrors):

Z71 (note: the door handles are unique, they aren't entirely chrome)

Early 2007 LTZ:

I'm unsure when the changeover to the chrome mesh grille, chrome handles and mirrors took place, but all these early models with VIN/build stickers visible show 6/2006, 7/2006 or 8/2006 production dates. I will keep looking to try and lock this down further.

Here's a chromed LTZ with a 12/2006 build date:

Another thing to note on chromed vs. non-chromed LTZ is the center console changed slightly. The chromed models added some faux wood trimming over the cup holders and empty spaces. The non-chrome have the same center console as an LT.


A White Diamond Edition was added for 2008 Tahoe, Suburban and Avalanche LTZ models, as well as Yukon and Yukon XL SLT models. The main feature was the White Diamond Tri-Coat paint, but some extra chrome trim (note the running boards) and fancy wheels were added as well. For 2009, White Diamond Tri-Coat became a normal color option and the special edition was dropped.

2008 was also the first year of the Tahoe and Yukon Hybrid models.

Tahoe and Suburban LTZ receive new rear bumper and side moldings. Avalanche LTZ only gets the moldings.

Z71 models get body-color handles and mirror caps

Yukon Denali and Escalade/ESV/EXT receive a flex-fuel badge for the first time.

Escalade Hybrid is introduced.


Deletion of the GM 'Mark of Excellence' badge from the front doors. The flex-fuel badging is changed from yellow to green.

Interior door panels are revised, window control area is slightly thinner.

C-pillar trim badge is deleted for LS and SLE models.

A 75th Anniversary Diamond Edition Suburban is introduced to celebrate 75 years of the Chevrolet Suburban nameplate. Based on the LTZ trim, it features several special details including badging, wheels, roof rack and interior stitching. Note the Escalade/Denali-style roof rack side rails.


Tahoe, Suburban and Avalanche LS get body-colored accents.

Avalanche LT and LTZ offers body-color rear trim depending upon paint color.


Yukon and Yukon XL SLT offer a special Heritage Edition celebrating 100 years of GMC Trucks.

Official GM press release:

NEW YORK – It is no coincidence that the 2012 GMC Yukon, Yukon XL and Sierra Heritage Editions will debut at the New York Auto Show. A century ago, the GMC name first appeared on the front of a truck at this very same event.

Commemorative exterior badges on the doors of these special models feature the original GMC logo design that debuted on the 1912 range of models, which included gas- and electric-powered trucks designed for the most demanding among early drivers. The script is surrounded by the words “Heritage Edition.”

2012 Heritage Editions will be offered on Sierra 1500 Crew Cab, Yukon and Yukon XL models in SLT trim. Three colors will be available – a new, exclusive Heritage Blue ($195), White Diamond ($995) or Onyx Black (no additional cost). Interior colors for the Yukon are Ebony and Light Tan.

Yukon and Yukon XL full-size SUVs are equipped with:

Unique “Heritage Edition” exterior badges
Embroidered front floor mats
Embroidered front headrests
SLT-2 Equipment Package with 10-way leather memory seats, headed second-row seats with power release, power-operated liftgate and heated side mirrors
Additional content – including 20-inch wheels – is optional 12/Mar/0330_gmc.html


Flex-fuel badging is deleted.

Final year for Chevrolet Avalanche and Cadillac Escalade EXT. Avalanche offers a special Black Diamond Edition.

Final year for 2500 Suburban and Yukon XL.


No major changes, final year for GMT900 SUVs.

Now, to move on to the Silverado and Sierra pickup trucks.

2007:First year for the all-new Silverado and Sierra. Not to be confused with the [GMT800] based Silverado/Sierra Classic.

The VortecMax package included the 6.0-liter 345 horsepower Vortec V8 engine and heavier duty transmission cooling. It also included a door badge seen below. Another way to spot these models is the exhaust, which exits straight out the back vs. the curved exhaust that exits behind the rear tire on all other Silverados and Sierras.

Note the larger chromed grille and bumpers on HD models, also note the engine identification badge on the hood.

Silverado and Sierra 2500HD and 3500HD models receive major updates including a stronger frame, new wheel choices, new front bumper, grille and hood as well as a revised trailer hitch on the rear bumper.

2011 Silverado 2500HD Regular Cab W/T with aftermarket Knapheide brand work body [GMT911].

Notice the difference in trailer hitch from the 2007-2010, to the new 2011-2014 model.

The hitch is much wider and has larger openings for the trailer safety chains.

Silverado 1500 LS and LT get a new front bumper. Note the black plastic fascia is now painted silver and the end caps go from body-color to chrome.

2012 Silverado 1500 Regular Cab LS.

2012 Silverado 1500 Crew Cab LT.

LTZ models also get a new body-color grille as standard equipment for 2012.

This grille is also used on LT and LTZ models with the optional Z71 Appearance Package, but the lower plastic fascia is painted body-color.

The Z71 Appearance Package is also now offered on 2500HD and 3500HD models with single rear wheels.

GMC offers a Heritage Edition package on Sierra 1500 SLE and SLT models. Unfortunately, there wasn't a good shot of the badging shown, and this truck was also listed as the wrong color. Heritage Blue Metallic was exclusive to the Heritage Edition, but has also been offered in the past as Laser Blue Metallic.

Flex-fuel badging is deleted from Sierra Denali models.


Deletion of flex-fuel badging across the entire Silverado and Sierra line.

No other major changes, final year of the [GMT900] based 1500 models.


Final year of the [GMT900] based 2500HD and 3500HD models. No major changes.
