I'd be cautious about running this kit. One of the "benefits" of a coilover is that you maintain max wheel droop which limits max CV angle. Seeing as how this strut is longer than a stock unit w/ a "puck" attached is a bit of a red flag, combine that with a lifting knuckle and ... yea.

Is there any data regarding what their knuckle does on its own? We know the Tremor's raises it even further. If one were to combine a stiffer spring rate with a knuckle that further provides lift, you're at the limits of the CVs. The street angle of the CV isn't as important as the angle at max travel. That's where you break shit, when that loose wheel spinning finally grabs at max angle.

There’s a thread on the tremor forum that goes into it more. My understanding is that the knuckle does not provide any lift but rather slightly moves the location of the hub in relation to everything else to lessen the cv angle. The difference vs a regular knuckle are minor but someone took measurements on that forum and some good comparison photos.

There's a thread here w/ measurements, it appeared to be about ~3/4 of an inch lower in relation to where the LCA mounts which is by for all intents and purposes a lift that increases the angle of the CV shaft. This is also likely the reason that the tremor's half shaft is an upgraded unit.

I’m not so sure the oem tremor or icon knuckle adds lift but rather relocated the uca, tie rod, and sway bar end link back up an inch to correct geometry/stiffness. Just my $0.02

The distance from the top of the bottom ball joint reception area of the knuckle, where it contacts the LCA, to the hub opening dictates the height of the ride it provides.

Not sure if that measurement was taken.

I threw the stock knuckles on the curb…

Stock vs icon

 

[Cooder_Graw]

Not great detailed pictures sorry. I was in work mode

 

[HammaMan]

Stock vs icon

got this measurement from each by chance?

 

[Cooder_Graw]

No . I still have the stock . But no I didn’t

Where did you purchase the kit?

I would assume it was purchased from here: https://www.iconvehicledynamics.com/products/?page=2&year=2021&make=Ford&model=F-150 but I don't see a kit with the uprights and shocks that don't have an external reservoir, so I don't know what kit it would be.

any chance you could grab a pic of the cv axle angles on your truck now?

We’ve asked several times, don’t think it’s going to happen

 

[TheGoatman]

Unless looking for full droop, jack up your truck to the ride height given here and that’s the cv angle.
