I have to say, I was skeptical given the price of Icon's products compared to a lot of other suspension companies I have researched before buying these coil overs. I installed them on a 2009 tacoma 4x4 double cab long bed. These are hands down the best suspension upgrade I have made on any vehicle ever and I have lifted over a dozen different vehicles over years. The truck rides and handles better than from the factory. I left them adjusted to the height they come in from the factory which is about 2"" of lift. The truck sits level from driver to passenger side. Installation is not too hard if you have proper tools. Its also nice that they come ready to install. No coil compressor needed. Just jack up the truck, remove the steering arm, disconnect the sway bar and cram them in there! I was able to get the truck aligned at a local shop and at that height setting they were able to get it within spec with my factory upper control arms. Now I just need to save my pennies for the rear shocks and progressive add-a-leaf to get this thing back to level.
