I would like to level the frontend of my truck and I was wondering which is the best kit for it?  I see different ones out there that are made of different materials.  They all seem to be within the same price range and I was wondering which one is the best material.  I was also wondering if it is going to put a lot of extra stress on the frontend componets?  As always, thank you for any help and information.    

For 05, a 2.5" should level it. You will put more stress on your suspension, but its not that bad, just talk to a mechanic, or maybe even a Ford dealership mechanic for advice... You could go w/ a 3" body lift, which will keep suspension components at their proper angles. I know you posted this back in September, but I saw you had no responses... you may want to consider f150online.com for quicker responses to stuff... look me up there too... Hope this helps.
