I don't care how fast your truck is accelerating as long as you stop! I put on the front set about a year ago and love them. After the repair calipers I got from my local auto parts store failed in the rear (again), I ordered a rear set. Installation was easy. The quality is excellent. Pedal feel is greatly improved. I now have front and rear kits on my 7.3 F-350 and am very happy. This is a quality kit at a great price. The calipers you buy from national chains are rebuilt with mediocre parts, that's the real deal. All the equipment you will need is provided and is of a higher quality than what you will receive from them. Do yourself a favor and get this kit, you won't regret buying calipers or rotors every two years. you know what i'm talking about
