opinions on front diff spacers with 3" Pro Comp lift

I got a 3" Pro Comp lift kit with rear aal. After installing springs, shocks and the sway mount. I was looking into the diff spacers that came with the kit. Are they necessary? I've been reading on here, they cause more damage than good. Just wondering if I can consider the front done without them.

 

Are you talking about the differential drop? If so, not needed.

 

I'm thinking that's what she is talking about.....and most people say don't use it.

 

do not use it... not like the 1st gen where CV angles were a concern... in stock form CV's are almost angled up!

 

Thanks guys, in that case, my front end is DONE! just have to get it aligned
