Never used it - the real reason I'm responding is not to tell you that, but rather to point out that it looks like it's missing more than a few items.
Go to a couple of Suzuki aftermarket vendor websites - try Low Range Off Road, they have downloadable instructions for their kits - look at the contents of their body lift, and suspension lift kits - compare them to what is being offered here.
Maybe ask this guy to send you the instructions, see how they compare.
