Lifting IFS is tricky and places added strain on the front driveline. Could your aesthetic objective be achieved by adding 1" of front lift and 2" of rear lift ?

Yes, now I get it. As you say, extra droop increases fender space, helps stuff bigger tires, but the amount of lift that can be obtained this way is limited by CV travel. As you say, obtaining clearance in this manner may not be good for the CVs. So this type of lift works better for the rear...

I like the idea of a hybrid, like Zone's. I see pros and cons of each type of lift, so do a moderate amount of each lift type, instead of a larger amount of only one type. Also, I think having equal amounts of perch lift and top-hat lift will minimize the downsides of each.

Thanks, it's great to be able to evaluate the geometry of different types of lifts, so there should be no surprises. On the front perch collars, I should be thinking in terms of a two-thirds ratio? So a 1.5" perch collar should give me about 1" of perch lift ?

Suppose before installing the perch collars you had 8" of travel, 4" up and 4" down. After you lift 1" via perch collar, now that 8" travel is divided 5" up and 3" down? I'm pretty sure that's how the perch collars work. The only way to absolutely ensure clearance for larger tires is to...

So I think it's pretty clear you're saying there's nothing the end user can do to ensure security. You're actually saying that. After saying there's nothing the user can do to ensure security, then you refer to a "stand against technology." So, accepting the reality that "smart" phones...

Agreed, changing the ride height via perch collars does not ensure that there will be no rubbing with larger tires, because, as you say, the travel has not changed. Not having insurance against rubbing does not mean the perch collars are worthless. When you're trying to turn with large...

Holy crap! You think the security patches work ? ! ?

100% Agreed, the strut travel remains exactly the same. The point I was trying to make is that increasing ride height via the perch collar means there's now more room above the tire. It got a bit wordy, but that's why I was trying to talk about tire travel vs strut travel. Use the perch...

Here's a youtube vid that explains it pretty well

If I'm reading the words correctly, then Mudlight did it exactly right. A person who increases ride height 1" with a perch collar would also want to use an external 1" top-hat, to restore the front tires to the factory's equal amounts of uptravel and downtravel. Since he lifted with factory...

I guess since the perch collar only increases ride height, and does not change travel, the 1" perch collar would allow the tire 1" of increased uptravel and decreased downtravel. So a person who increases front ride height 1" with a perch collar would also want to use a 1" top-hat up front, to...

Thanks, awesome ! Now that I think I understand what perch collars are, it looks like Mudlight increased his front droop by 1" with the RC level kit. The 1.5" top-hat spacer out back is ok, because of the solid axle out back. I'm still kinda surprised that he needed the 1" body lift, when...

Now I think I understand. The perch collar is like an internal spacer? That's how it lifts the vehicle's ride height without changing strut travel? In IFS jeeps I'm used to seeing them just call 'em spacer lifts, so that's why I needed to learn a new word.

Does pre-welded mean bolt-on?

No effect on suspension? Does that mean the collar has the same effect as a partial body lift? Just trying to learn terminology that's new to me. I guess the top-hat spacer re-locates the strut, thereby increasing droop? But the collar does not re-locate the strut, and does not increase droop?

Thanks, awesome! Since it seems the high-end struts can increase travel, I guess one would have to ask the vendor whether it's safe to use a top-hat spacer or perch collar (or whether the vendor's strut has already used up the 2" of extra droop that we have to work with).

Is the concern about the warranty because the perch collars are re-locating the struts downward, thereby increasing CV downtravel ? Just trying to learn new terminology. It would seem like a good strategy, if the CVs can handle the extra downtravel.

Mudlight is running 38s with the following set-up. I saw this in someone else's build thread, so I'm asking my questions here not to hijack : I'm trying to visualize which types of spacers extend downtravel (wondering what the limits are on downtravel for the front CVs). Do the perch...
