I also posted this on the Slider Recommendations thread and the Consolidated Slider Info thread.
If you have a 5th Gen, I recommend the 4xInnovations bolt-on sliders (
Welcome to 4x Innovations - Hardcore Toyota Rock Crawling Armor). They are the strongest and best designed sliders for actual use.
I am a licensed Civil Engineer in NC, SC, GA, and AZ and have been doing engineering design for 29 years. When I wanted sliders for my “new to me†2011 4Runner, I spent 6 months reading and researching everything I could find because I wanted something that was well made, strong, and affordable. I looked at everything from weld-it-yourself kits to save money to bolt-on and, frankly, nothing really compared to the build quality and strength that was evident in the 4xInnovations design. I could tell that these were built the way I would build them and that was what I wanted. You can tell that every opportunity was taken to make them stronger in a way that minimized the stress transferred to the frame rails. Pretty much all of the other bolt-on sliders attach with between 6 and 10 bolts per side, but these use 17 or more on each side. Watch the video on YouTube for more detail at YouTube. There is also a video on installation and a drop test video (which nobody else has done).
My only problem was that the website said 2014-2018 and my 4Runner is a 2011. I bugged Adam at 4xInnovations for about 4 months, sent him photos and measurements, called him and talked about the install, and finally we concluded that the sliders would probably fit my 2011 after all. I placed the order and couldn’t be happier. Installing them was a breeze (after three coats of bare metal primer and three coats of satin black). I did it myself using a floor jack with a 2x4 to spread the load and the only difficult part was getting the KDSS accumulator pulled away from the frame so I could slip the slider underneath it (it is pretty tight). Once everything was mounted, I added grip tape to the top (12â€x2†80 grit pre-cut strips from Amazon) and they look fantastic. I attached a couple photos below.
