Silverado HD release dates?

Most likely next year. I myself would wait for the nice interior change in 2015. Rumor has it anyway :R

All HDs will be 2015, no 2014, according to our dealer. He says the 2015 2500/3500 will be on his lot by the end of September 2013.

The 2015 will not be on any lot prior to January 1, 2014. EPA certification rules do not allow a model year 2015 to be sold during calendar year 2013. They can only be sold in model year less 1 calendar year.

I'm NOT the dealer, just the customer. I figure he, whose family has been a GM dealer since back in the 1940's, knows what he tells his customers. Also, in todays world, there is no reason to follow the law, no one else does.

I had heard early spring on the HD trucks.

I wouldn't expect much change in the powertrain department. GM just did a big refesh on the chassis/drivetrain in 2011. I suspect the new trucks will primarily be cosmetic both inside and out. Imagine the 2014 1/2 tons with a more agressive hood. Were probably a year+ away before the new HDs hit dealers.

I was at a GMC dealer this past week and they had their first new 2014 1500 Sierra there. It was nice. The HD's come in 2015 model year, likely late 2014. You can find info about them online, but no real dates.

Nah dont need one mine has only lived about half its life.
