I was thinking about putting on the Deaver+3HD on my '17 due to having some added weight on the bed with bed rack, RRT, camping gears etc... But I am going to wait until I really needed to change later for the reason the will and do squeaks and make noise no matter how much lube you do beforehand, have to keep them lube after every rain and so on.... I have replaced the leafs on three of my old Tacoma's and they all make noise after a while. Unless is necessary ( like you have a lot of weight in the bed all the time), installing it just to fit 37's and have to deal with gas milage loss and the problems/noise that will come with that later I don't think is a smart move. But to each his own!
There are a number of benefits the Deavers/Icons have over stock leaf springs aside from the 37" tire factor.
