Currently I have 2" pucks up front and 2" blocks in the rear on my 2WD. I've been wanting a more level look, so I purchased the RC 1" blocks to put on the rear. However I've been thinking maybe I want more height up front instead of lowering the rear. Currently have 2" of rake.

Looking at 3" lift kits I see there are a few that have UCA's and spacers. Since I already have the spacer installed, can I add UCA's to give me another 1" of lift to the front? Curious if the UCS actually adds height or just works better for systems that have height added thru spacers/shocks.

 

The control arms don't give lift. anything over 2" of lift can really impact ball joint angles....that is what UCA's do...correct angles due to the lifting or lowering process.

 

Thanks @Physh1

That's what I was thinking, thanks for clarifying.
