Anyone used this diff lowering kit? Do you need it if have only 3" lift? I'm installing a calmini UCA and SAW torsion bars, along with Calmini AAL and shackles.

What do you guys think?

Which shocks do I need? I'm considering buying SLR's bilstein's extended shocks to go with the calmini stuff.

Any info/feedback on the proper shocks with this setup?
