A little help please

Hey guys!

I just installed the RE 5.5 longarm kit with ACOS coil spacers, that are set at the lowest setting at 1 1/4 of extra lift to the front. If I were to lift my backend another inch to provide for offroad weight, and the front another inch, would I have to replace my front shaft?

Oh and another problem. My draglink and tierod keep hitting my factory posts for my discos, Ive settled on welding new tabs for them from JKS, but are these the best thing to use, does anyone have any experience with them? Should I get the 1 inch raise or 2 inch?

What are you running for steering? If it's stock stuff than you have to have your caster way out of wack.

The driveshaft is going to depend on where you front axle is located.
