SPC UCA Contacting at full droop?

[gimlithepirate]

I've got an Eibach pro-truck lift on the second perch, and SPC uppers at the "F" setting. When its fully drooped out, I'm just barely getting contact between the ball joint on the SPC upper and the shock tower. Any idea what causes this? Do I need to work on my alignment to avoid this, or is this a strut issue?

Wait it’s hitting your spring or the actual shock tower?

The spring. My brain did a dumb and was thinking of that whole structure as "the tower."

How far pushed in on the UBJ slider? The contact is usually because, depending on how you have the LCAs set, the upper ball joints have to slide in kinda far. Also pushing the UCAs forward brings the UBJ closer to the apex of the coil (furthest exterior side, because they're round), whereas stock they sit a tad behind the coil.

I have the half tube, half forged style SPC arms at position F and the ball joint slider is about halfway in, my lcas are set all the way forward with the lower cams, and I've got maybe 1/2 between the UBJ and coil at droop, but my UCAs also don't appear to droop as much as I've seen for some reason

Yeah, its because I have to push it all the way in to get my alignment right. I'm trying to keep the tire as far forward in the wheel well as I can get it. To get to an acceptable alignment, I basically had to go F, all the way in, and bring the LCA back just a bit.

Sounds like I will need to redo my alignment again. :lalala:

With my Kings and Camburg UCA's I was able to rotate the spring in such a way the UCA barely cleared at full droop. Just rotate the spring so it droops between 2 coils.

You’re that guy at work that comes up with the easy solutions, AKA “work smarter, not harder” lol
