3.0 Duramax Trailboss???

Recommended Posts

So I’m currently eyeing the possibility of upgrading my 07 classic Duramax to the 3.0 in the next few years. 
I’m more of a Silverado fan than a Sierra. I see that the 3.0 is already available for the AT4 Sierra but not the Trailboss on the Silverado side. 
Any guesses on the likelihood that it will become an option at some point??

Won’t hazard a guess on the branding aspect but the lift kit itself is available through the parts department.  Not sure that you’ll want to ask them to do the install - if it’s a technical reason for it not being available you’re ‘out there’ at that point.
