Has anyone found any ~2" drop shackles yet? It is the most basic part on the truck. Not sure why it's taking so long to develop...

I'm not sure you really can remove that spacer. The Suspension Deep Dive article listed that spacer as being there because the spring packs were thinner than in past years. And removing the spacer could impact ride if it changed the curvature of the leaf springs at rest, I really don't know. Also looks like the U-Bolts would have to be replaced as I don't think they are threaded up high enough to account for the removal of that spacer. Just some things to think about, but I have never removed or added spacers to a leaf spring setup, so I am just speculating.
I removed my rear blocks 8 months ago rides the same and used same u bolts ??

HI People.....I just took out the rear end leaf spring spacer. The spacer is
1-1/4" inch thick. My original bed height was 40 1/4", now with the spacer removed is 39" inch now, front is 37' inch so I now have a rake of 2" inches now. I add a few washers to make sure I had enough threads on the 1/2" thick U bolts. 2 hours for 69 yrs old man, lol The spacers are not tapered either, they are square in shape too.

I have a 2021 Lariat 6' 7" bed with Max Tow Package. Don't know if others have the same? I pick up my truck on 3 weeks ago...

I just installed the Ford kit for the 15-20 on my 21. Dropped it 1 3/8. My 2wd didn’t have any blocks to remove. Rear is now 1.75 higher than front. Super stoked the tailgate is a little over 2” lower!

Installed the included shims, zero driveline vibration. Didn’t use the crazy instructions except for the torque values. Had a lift and rear end stands. Removed the spare, left the rear wheels on. Glad I had air tools and long pry bars. Doing this with just a jack and stands is a young man’s game…..

Looks amazing! Just ordered the kit, great to have confirmation and photos of the kit/truck showing it works on Gen14! Will be installing on my 2WD SuperCab and will post photos afterwards.

Did you guy use an shims in the rear to align the pinion after lowering? Also, does anyone know if removing the rear block hinders the auto adjusting headlamps?

Hasn't bothered mine and I didn't need shims.

Do you know what your measurements were prior to the install? I’m thinking of doing this and raising front an inch to make level- also have a 2wd stx but I have the 18” wheels and sits super low in front- going to be changing to 20” fuel wheels- want the leveled off-road look without killing mpg and keep it easy to get in and out of.
