Installed BFG KO2s 265/70/17 and Toytec Boss coil overs on my wife’s 2015 Trail Premium 4Runner today. I have installed 2 different sets of coil overs on my 2009 Taco so was familiar with the process. The one thing that caught me up was the KDSS sway bar, but after a search on the site I was able to complete the install. While I had the wheels of I used a new Fluid Film product that I highly recommend: NH Oil Back N Black. It’s like fluid film but has a black tent to cover any rust. Comes out amazing! Pretty much set the boss coil over at 1” of threads to get the from sitting just below the rear.
