Rear lowering shackles - prior gen fit 2021?

[JRev]

Hi @JRev,

I did these.

Installed in about 45 minutes using a rack. Came out perfect. Tuck is nice and level now.

Nothing else needed? Just slap those on and go?

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 great! I'd love to install this on my 22 XL STX, Space white, same package and wheels as yours.

I used the shims.

Did the M-3000-HA kit come with shims? TIA

Yes the kit comes with shims.

No shims needed? I'm debating on this kit.

No shims. Just shackles very basic. Here are pics of measurements of my 2021 f150 vs my new 2023 f150. 21 has drop shackles, 23 does not.
