I installed the Teraflex 1.5" lift on my 16 TH without any real issues and so far so good from what I can tell. I was able to align the front camber and toe but not the caster. I probably just have to clock the struts some more. However, since caster isn't going to ruin my tires I probable won't go through the butt pain of clocking them again. As for the rear, camber and toe are good as well. I had to pull the top of the rear struts further outward then the instruction say to do initially when installing them in order to get the camber in specs. But that is a none issue since the instruction later say that what I did may be required in order to set the camber. Furthermore, nothing about the kit seems flimsy or easily breakable. I would recommend this kit to a friend. One more of thing of note; I went with Teraflix because after days of reading how Daystar and ATP kits fail a proper alignment regardless of what the companies claim, I simply didn't want the headache. Teraflix will actual align if you follow the installation instructions.
Just remember, the instructions do not say to remove the gas tank skid plates. Do yourself a favor and remove them - 3 bolts for each plate. You'll save yourself a headache trying to install the trailing arm brackets.
