Are you confusing this with Cam phasers?

No, I think they installed a better valve but I could be mistaken.

Well, probably, they are still in use on the 2021 f150 as per my google search, but they look electric not vacuum.

This was a great review of the ‘21s suspension changes. Looks like IWE still retains use of vacuum,
But it’s probably enhanced electronically now. The new booster less electronic master cylinder is interesting. It’s a must for hybrid setups.

Copper lines FTW.

I believe I either read or watched a video that stated it was going to be electronically controlled.

In order to appreciate the IWE system you need to park the Raptor in a mud hole, then get out of the truck and inspect both front tires. Then you will truely understand the IWE system.

How is this IWE thing still a problem??? I bought a 2020 802a in august drive it 5 miles and the “grinding” was horrendous. $73K truck and has to immediately go in the shop for a repair that seems everybody knows about

For the record, it's not everybody, just the ones that have the problem complain. I've had mine for 11 years and never had a problem with the iwe's. It still seems like a problem idea though, looks like the gen 3's have been modified a bit.

Looking into this a bit further... And definitely relates to my recent experience. The IWE failures seem to occur more often during cold temperature. Mine started acting up below freezing.
