I'd like to upgrade my rear shocks on my stock FX4. I'm using a 2020 F-150 search and not 2021 F-150 b/c a lot of places don't have something for the 2021 but I'm guessing they are the same shock in the rear. Seems like my choices are

- Fox 2.0
- Bilstein B8 5100 ( BIL-33-253190 ) 0"-1" lift
- Bilstein B6 4600 (BIL 33-253183) no lift

I'm guessing there is no reason to go with the B8 if I don't want to lift the rear? The Fox are a little more expensive but not sure they offer anything that the Bilstein don't.

Thoughts?

Stage 3 has just the rear Fox, relatively inexpensive. I used them on my Ram after I lifted it, huge upgrade.

I pulled the trigger on the Fox 2.0 from Stage 3. Will report back if I can tell any difference when I get them installed hopefully next week.

Just finished the install. Will test them later today. Here are my tips:
1. jack up on the rear axle and install jack stand. I did one side at at time.
2. remove rear wheel one side at a time (gives you way more room to work. it can certainly be done without removing the wheels but it's just harder)
3. unbolt stockers using an impact gun (15mm bolt head and 18mm nut)
4. when installing the new shocks put the bolt through the bottom eyelet first because it's easier to manipulate the top of the shock to line the bolt up. pushing from the bottom up is much harder as it's how I did the first one.
5. cut the retainer band so that the shock extends to the upper mount
6. not likely you can run the bolt through as the shock extends so plan to use both hands to pull it back down (not easy) and get the bolt ready to run it through as it extends back up while you slow it down with your other hand
7. torque to 66 ft lb
8. stand back and admire your work
