    i have an 05 silverado 1500 crew cab short box 5.3L LS The sticker on the inside of the drivers door is so faded you can't read it. How can I tell what my gear ratio is? Is it stamped on the axle maybe?? I call the dealership with the vin # but they are taking their sweet time getting back to me.. According to the manual it is either 3.42 or 4.10 I'm thinking its the 3.42 cuz I get around 19-20 mpg on the highway averaging 70 mph or so.... Any suggestions????:happy:

    There is also a 3.73 gear ratio. You can look up VIN decoder codes here on the site and thru your vin it will also give you the RPO codes for your truck. Also the RPO codes are written in the glove box. You are looking for a GT and a number.. there is an RPO code listing here on the site as well, and that will tell you the gear ratio.

    Just use tow haul mode. No problems with 6K plbs when i had my 06 i had the 3.42s and never had a problem pulling 7K lbs a few times a year. Just make sure you get a brake controller for the electic brakes, and a wieght distribution hitch.
