Caster maxed out?

So I got a 3" rc strut spacer lift installed. I have 16x8 rims and 285's. Everything else is stock. I went to VIP to get it aligned they got the toe and camber aligned. But they didn't do the caster, the paper they gave me says "seized, cannot adjust" on the caster I called them and they said that it wasn't adjustable because it was maxed out. Are they being idiots or do I need new UCA's?

 

Are they seized or maxed?

Even if they aren't seized, you're not going to get decent caster with a 3" lift and stock upper control arms.

The paper says seized

 

So you need to cut out the cam bolts and replace them to regain adjustability. You're still not going to get a whole lot of caster out of them with your setup.
