The only thing that the new shocks will do is as you stated in your first question. It will allow you to have full range or articulation.

You are correct you don't need to mess with the brake lines with the shackle lift kit.

As for your second question the answer that someone already gave to you stating that you don't need to have new shocks is entirely correct. Any other questions just ask.

I'm running stock brake linenes right
now. The rear suspension just hanging down,
tires off the ground. Brakes lines were okay just
enough slack. Articulated i'm not sure yet.
I'm still adding longer lines.. Revolver shackles are next!

well, decided on the AAL 2.5 system. I'm not getting new shocks however, I can't justify replacing brand new Bilstien ORs this soon. I'll sacrifice some articulation.

That's kinda what I'm thinking. I plan on updating them a little down the road.

Just sell off the Bil's to someone who has a non OR 05-06 X.

I can see the rears an easy sell, but the fronts would be a pain in the butt.

You don't need to change the fronts.

Sorry getting my message boards mixed up.
