Just put this lift on my '09 wrangler last night. Very easy install. The directions list a 3-4 hour install time and it fits that time frame. Had a friend help me with the install. With dinner/beer break it took us just under 5 hours. I got the Series II kit from rough country (part #634). This kit includes the front and rear spring spacers, front and rear shock extension brackets, rear sway bar links (you move the stock rear links to the front after you finish the lift), rear brake line extension brackets, and a rear track bar extension bracket (when you put the lift on the bar moves off of center by a 1/4" and this bracket corrects that, a purely optional part but i went with it anyway)
Just a note on installing the rear track bar bracket. When bolting the bracket on and bolting the rear track bar onto the bracket I would suggest putting them in with the nuts to the rear of the vehicle. When you install the new rear sway bar links you have a small (3/8" to 1/2") clearence between where the new bracket sits and the top end of the new rear sway bar links. Switching the bolts around so the nut faces towards the rear of the vehicle gives a bit more clearence back there.
After the install realigning the draglink to center the steering wheel with the tires was very easy to do. Jeep drives fantastic, keeps the same stock feel, levels off the front and back, and looks great. With the 17" rubi wheels and 32" tires the lift looks perfect. I strongly suggest this lift for anyone just starting the process or wanting to add just a bit more space for larger tires
