Both sites dont seem to show a specific 21 rear 3 block kit
looks like they offer front and rear combo kits including a puck and rear block but again both sites show the old style u bolt in the pics
maybe you request it when paying or something.

Yes, just specify in the notes that you need 21+ U bolts.
I purchased just the U bolts from auto spring and they were very good to deal with.
Stage 3 has similar pics and info for '21 3" block kit. Might ask them if they have the long round bolts in stock.
From site:
Fitment: 2021 F150 4WD & RWD
Ride Height Note: this rear block adds 1.75" of ride height on 4WD F150s as a replacement for the stock block. On an RWD F150 without a rear block, Auto Spring's blocks will add 3" of ride height. Aftermarket shocks are highly recommended on RWD F150s and are recommended for 4WD F150s.
I just had 6112s installed, and went to the highest setting (2) but got just over 3 out of it. Hoping it settles a bit but the ride is great. I want a 3 block for the back, looks like the u bolts are different now.
Who makes a 21 f150 3 rear block kit with proper u bolts. Cant seem to find one
to the guys wondering about the 3 rough country kit I got to take a truck with it installed and it drove great., was really impressed. I came from a fox truck and ride was more comfortable with the RC. I just wasnt sold on the long term quality of the kit which may be a non issue. Wasnt sure of the rear shocks it had though
Is it possible you got 3 because the 21 is redesigned? Kind of like the fox kit if you didnt adjust it youd get more than a 2018 would due to new geometry. Still confuses me though.
Yea good point, def possible. There was another guy online that had them installed and didnt mention getting 3 out of them but I guess if you didnt measure before and after install you would just assume you got 2.
Has anyone that is over 2.5" lifted in the front replaced their UCA's? If so what did you use?
I finally have an appointment on the 23rd to have my Eibach kit installed and I am trying to see if my 2015-2020 Icon UCA's will fit the 21. I see some places list 15-21 UCAs and other places list 2004-2021 and then some list just 21+ UCAs.

I did not replace mine.
I remember reading somewhere that 2021 UCAs are different than the previous gens.
Is everyone happy with the camber on their trucks after alignment, if so which kits? Please state if the alignment shop installed any extra parts to get it to within spec.

I just had my Eibach kit installed today, so I am trying to get an alignment done tomorrow. I will let you know when I actually get it done.
