that kit doesn't include much of anything that is useful.
the control arms suck. you don't want the drop pitman arm. it's basically just some low end shocks and springs with sway bar links.
for the most part, your "suspension" consists of the following components: springs, shocks, spring isolators, brake
lines, sway bar links, control arms (2 upper, 2 lower), track bars, track bar brackets, bumpstop cups, jounce bumpers, and driveshafts.
a lift will normally require replacing or modifying all or many of those components.
In addition, you may also need to regear the axles and install brake & steering upgrades to accommodate larger tires. You may need a SYE and/or DC rear driveshaft. Welding and fabrication may be required for some modifications. During installation, you will also need cycle your suspension to full compression, full droop, and full flex. You may also want to add a 1" MML + BL, which will help many things along the way. with a d35c rear axle, you also need to consider upgrading.
as for how good the D35c is, this should answer your question:
