We have the fabric sportster in our F550.I put them inlast April. They are just a bolt in deal. you will have to install and route the air lines and wiring for the compressor. I love all the adjustabilty. they are not plush, the fabric is very much a working fabric. my first experiance with them was a 'workhorse' in my tool truck. sat on it every day 5 years five years running and it still looked good.
