2008 Chevrolet Tahoe LT -- gear ratio?

[pacem]

I have an 08 Tahoe, LT, 5.3L, what is the gear ratio? I haven't looked at the SPID sticker yet to identify yet. 3.08 or something else?

Probably 3.42... but my 08 Suburban LTZ was ordered with 3.73 gears.

I get that the Suburban had 3.73.. LTZ and it's a towing machine.

3.42 is not bad. Almost as good as 3.73 but should get much better MPG.

The 2006 6.0L/4L80 silverado got 12MPG on the highway and 10 in the city. 3.73 gears.

Does the 2008 LT have a class 4 hitch? It looks a little smaller than the class 5 I had on the 2006 Silverado.

My 08 has a RPO of GT4 which is 3.73

This will help

2007 Tahoe 2wd 5.3 with 3:42. Tows terrible. Would like to try 3:73. Any input?
