Installed on the obsolete 2011 Premium class. Super easy install, I recommend sanding the paint around the top of the ball joint that fits into the steering knuckle with a wire brush, taking the steering knuckle out and putting lube there, cleaning the pull studs and rethread and use a non-stick coating. and on the inner tie rod end. I rode this kit for three weeks and it rides better than it did when I had it in stock. Also catwalk springs and new A-pillars. This baby is smooth. Also go ahead and get the back white LCA line.
