Eibach Front shock install question

[Zarati]

I am installing Eibach shocks on my 07' Yukon. I chose them ooverv 5100s simply because they are supposedly a little softer while still firmer than stock. Very similar design though , and utilize the same grooves for adjustable lower perch. Extended length is about 3/4" longer than stock. Should allow similar droop to stock even with 1.25" lift.
Rears installed quick and easy. Front , I'm running into issues getting the lower mount up onto the control arm. Because of the extra length ot just doesn't clear. Sway bar is disconnected but the upper control arm is bottoming out on a part of the frame that looks like it is designed to act as an extension stop.
Has Anyone else run into this issue with other installs? I can drop a control arm to make it fit. It just surprised me As I hadn't seen anyone else mention that.
Thanks

Sounds like you need to undo upper balljoint.
Hammer outward on the knuckle to pop it loose if stuck.
I've always had to undo mine (z71 strut) and to install lift spacers.

Is the collapsed length of both shocks the same? That part on the frame is indeed an extension stop. Upper control arms designed for a lift will allow more droop. Rough country for example.
Some lift kits require removing that stop. A limiting strap would be recommended at that point.

Thank you. After reading some threads on spacer installs, I tried a long piece of pipe placed under the bottom spring coil and over the top of the knuckle and pressed down, and that was enough for it to pop in place. Just barely, I think if I went for the tallest groove, I would have needed to pop the ball joint like you said.

That's a good question. I did not measure the compressed length but I haven't done the other side yet. I will now measure, as I would like to know as well.
