These shocks made my ride smoother. I noticed when turning on my stock shocks that my truck would bounce all over the place. Now it does not. I am a geek and not mechanically inclined but I was able to install these. Advice to getting these on..I wasn't strong enough to compress the shock so what I did was i compressed it before putting it on and held the shock with cheap $10 ratchet straps from Home Depot. From there just crawl under the truck put it on and then cut the strap off with a blade.
These lift struts give your truck a great ride. As far as getting 35" tires on your F 150 Good luck without doing some cutting. I installed 33s after the lift and the just clear without rubbing. I called Rancho They had me measure from the center of the hub to top of the wheel well it measured exact to their specs They say you can and seemed to care less what I told them. The reason only 4 stars.
