2024 Duramax Upgrades. Horsepower, torque and an all new allison 10 speed creating and increase in towing capacity from it's predecessor. 2024 gmc sierra 2500hd at4.
These components are relatively cheap upgrades that can be installed easily and if i run into warranty issues i can swap the stock back on the truck no problem. I bought it just because over the 2500hd but pretty much guaranteed i’d never fully max.
