Bilstein 5100's in front with stock springs enough to level?

Where is the best place to buy 5100's from? I want completely assembled fronts and 5100's for the rear. Also, what spring are y'all that had them assembled go with?

 

I’m not the expert but 5100 uses your stock springs so not sure you can get fully assembled

 

I can’t use my stock springs. One is broken.

 

So you can use 5100 with stock springs and get 2.5” level?

 

Yes

 

I purchased from hotshot off-road. Great prices, and excellent customer service.

 

Ok, I read the entire thread and no one mentioned if the stock UCAs contact the coil spring at full droop. I have a recently acquired 15 double cab SR5 4x4. Previous owner installed a 3.5 / 1.5 spacer lift that has to go. Dirt roads are the extent of my off roading. I want to do this once and be done with it. Would 5100s on the middle setting cause the UCA to hit the spring? A small rake would be fine.
Thanks

 

On my 2020 the middle setting with stock springs and no other modifications works fine with 285/75/18. Nothing hits anywhere.

 

Thank you
I have a set of fronts on the way.
