400 vs newer

[PolarBear]

I'm curious, what do you think the 800's do better than the 400's?

Power, ride, interior quality, ergonomics, overall capacity as a truck, to name a few.

They have superior brakes.

Most of those are subjective, which is what I figured.

Do they?

LS swap, Coilovers, GMT800 seat swap.

As much as I like the Gmt400 I also like the newer trucks.

Here’s one that’s not subjective- 400’s look waaaay cooler.

The brakes are night an day. I have the best of the best GMT-400 brakes on my 1-ton (big calipers, 3.5" shoes, hydroboost) and the 4 wheel disc, twin piston calipers, of the 800 are much better.... plus the front rotors slide off, unlike mine that are held on to the backside of the front hubs.

I actually have not driven an 800 truck, but a two of the GMT-610 vans, but they're based on the trucks.

I have not actived the newer ABS when it wasn't needed either. My truck (and it's always done it) will activate the ABS if a bump is hit while coming to a stop, and cut your braking ability even though the wheel are back down on the ground.

Brakes on both my 800"s don't "seem" any better than the dually, but it's not an apples to apples comparison because the dually has bigger brakes and is much heavier. My 07 classic has rear drums, the Yukon is 4 wheel discs.
Not saying you're wrong, and point taken regarding the ABS

I suppose I should have qualified it by specifying 8-lug.

Not necessarily, I just wanted to be clear.
Every GMT400 dually I've ever owned have locked up the rear before the front when doing a panic stop.
