By the time the plasma cutter somehow got loose on my truck last year, I had the following left from a Calmini lift:

Shackles
Add-a-leafs
Brake lines

I had done the following:

[*]Gotten annoyed at the crossmember and swapped it back out.
[*]Was too fed up with a stiff frontend and swapped back to stock torsion bars
[*]Figured I didn't need the arms and swapped back to stock arms with a balljoint flip for a better perceived ride and a homemade (and quite effective, actually!) alignment
[*]Broke both front shocks repeatedly and hated how stiff the rear was

The only thing I have left now? Add-a-leafs with a SOA rear, as well as the lift shackles to deal with matching the height of the front.

Beyond that, I wish I hadn't spent that much money on that lift kit. I wish I had taken it a little slower, not followed the "lift-in-a-box" that really doesn't apply to our rigs as much as it does to every cheerleader's Jeep. I wish I had spent my money adding to the lift parts in my truck rather than removing parts over the course of a year - with a just-as-lifted truck at the end of it. Now, being able to go with your own shocks? That's pretty cool of them.

The kit is, however, really high quality. They were also very pleasant to deal with, and I'm not going to bag on a vendor that supports our truck (and actually does it quite nicely, really).

Of course this is my opinion, YMMV, etc.
