I don't normally buy stuff like this, but I replaced the entire front suspension and the steering still "wandered" a bit on the Autobahn. Using oversized tires will cause the stabilizer bar saved me from my problem. I can't do a 70-80 on the freeway and the truck stays straight like a laser. The steering feels stiffer, the setup documentation was fun but very easy to figure out. The install was on a 2001 f150 Supercrew 4x4.
