21 AT4 steps and height difference with 20s (pics)

[Tjeli]

I took some pics this morning of my truck next to a 21 to show some differences.  The new "high clearance" assist steps are very nice.  Also, the ride height looks quite a bit taller on the 21.  My truck has 3K miles on it.  The difference looks to be more than just the tire size. (275/65R18 vs 275/60R20)  It could be a combination of suspension settling and the 1" tire diameter difference.

I really like those high clearance steps! I like the old ones as well too.

Wonder why the ‘21 are higher?  Looks great.

Anymore pictures of those steps??? They look sweet! I've been wanting some Raptor look alike steps since I couldn't afford or didn't want to afford a Raptor ($97k can)

Mine will be about this height soon, I have the ready lift UCA and a 0.75" spacer until I can get the bilsteins.

The 21 is not taller. Its just a taller tire on the 20” wheel then the 18s.

The 21 also is missing the lower part of the chin spoiler.  I wonder if they did away with that for the 21's?

Good eyes on that one.. i trimmed it on my Ram, I may do the same to my AT4, unless I get an ADD bumper.

You dont have to trim it.  The lower part un-bolts.

Just take off the 12 small screws and the lower part comes off.  I actually had mine off but then I installed a front hitch for a home plow and ended up putting mine back on.  Hides the hitch better.

The tire size is one inch larger on the 21

Is that new step available from GM or somewhere? Curious on the mount underneath. On my 2020 AT4 step, the bracket hangs way below the already lower step and causes ground clearance issues on break over angle. If these new steps are much higher/lower profile, id be interested in buying a set.
Thanks.

They are on the GMC accessories page.  They are EXPENSIVE.  I was going to get some but they are too close to the price of an AMP powerstep and I would rather have those.

I just scored a set of the AT4 high clearance steps (take-offs) and put them on my Trail Boss....love em...AMP steps no longer wanted.
