I noticed right away it had bigger brakes on the rear than my 2016 model. I’m guessing it’s just more standardization of components. My 2016 rolled easier with 8.8 in but had that clunk too. The new 9.75 doesn’t clunk ever.At least in 2020 and 2021, ordering the 3.73 gearing automatically gets you the standard 9.75” rear diff/axle. Even regular cab shortbeds with 3.73 will get the 9.75”
For Max Tow and possibly some of the Powerboost trucks, the 9.75” will be the HD version.
It looks like you have the standard 9.75” axle with the L6 axle code, meaning that it is 3.73 with the electronic locker.
I have no idea if the standard rear brakes are larger than the previous gen. but the HD9.75” axle won’t clear 17” rims.
I read recently on this site there are 3 21/22 rearends. Model a, b, c in 3:73 ratio. Evidenced by the tag on axle.
