Chevy has finally revealed the full lineup of the which is now available with a 6.6-liter Duramax turb-diesel V8 with 910 lb-ft of torque and capable of towing a max payload of 35,500 pounds. Whew.

That 35,500 pound tow rating is a 52 percent improvement over the outgoing truck, according to Chevrolet via , and its thanks to a slew of changes made to the Duramax engine and the rest of the truck.

The ladder frame is stiffer, the prop shaft and axles are larger, and there’s a handy label specifying curb weight, gross vehicle weight rating, gross axle weight rating, max payload, and a few other specifications tailored to each truck based on its VIN. The trucks are also all longer, wider and taller with more interior space.

If you don’t go for the 445 horsepower, 910 lb-ft of torque turbo-diesel, which is matched with an all-new 10-speed automatic, there’s also a 6.6-liter V8 gasoline engine, which produces 401 HP and 464 lb-ft of torque, which is said to offer an 18 percent towing capacity gain over the outgoing model.

Compare all of this to the , which has a max towing capacity of 35,100 pounds from a 400 hp 6.7-liter Cummins diesel with 1,000 lb-ft of torque, or a less-powerful version of the same 6.7-liter diesel with 370 HP and 850 lb-ft of torque. There’s also a 6.4-liter gasoline option with 410 HP and 429 lb-ft with the Ram.

Ford also has a recently updated truck, , but has yet to announce any real torque, towing or power figures, but did claim its gas V8 would be the most powerful in its class.

Anyway, back to the new Chevrolet HD lineup, it will be offered in five different trims. The Work Truck, with the black grille bar backing the Chevrolet name, Custom, which is only available on the 2500 model and gets the body-colored grille bar, LT and LTZ, which get chrome accents, and High Country, which gets the big bow tie grille. The diesel trucks will get bigger hood scoops and Duramax decals on the hood.

The trucks also get a new, larger bed-side step that’s rated for 500 pounds now, a new 15-angle trailer camera setup with a feature that makes it possible to see-through the trailer that’s being towed as if it’s transparent, an easy-fill diesel exhaust fluid tank on diesel models, simpler snow plow attachment points in the front, and a new Park Grade Hold Assist that activates all four brakes on the truck, not just the parking brake.

Pricing will be announced closer to the summer, when the new HD goes on sale.
