Installed these on my 2015 MB Renegade Villagio 25' RV (14 build). To loosen the lock nut you need a 14 mm deep socket, which is accessible from above the stock fender. Did one side at a time, jacked it up with a 3 ton jack and turned the wheel to expose it. took 10 min. max. on the side. Can confirm the expected results: tighter steering, less sway. A nice bonus was that you CANNOT dive while braking. I was really surprised by this discovery. Sweet. OEMs are ridiculous. As for the price, it is. I think it comes with Territory (if you can afford one). Also bought and tested Sumo buttstocks and a Helwigrear stabilizer. The difference is that my wife is more willing to drive when I drive on the freeways. Another bonus!
