We include instruction guides with many products. These guides are to help the customer install our products, however we are not liable for typographical errors included in the guides. It is ultimately the responsibility of the vehicle owner and the installer to ensure that all parts are installed properly and safely on that particular vehicle. Our installation guides are simply a starting point, meant to help explain what the individual pieces are and where they should fit on the truck in most cases. We are not responsible for improper installs - every vehicle is different and it is up to the vehicle owner to make the best decision for their particular situation.
