The product could be better
When installing the Iron Cross HD Series Step Bars on my 2015 Silverado crew cab I found the instructions in lacking quite a bit. If it wasn't for a you tube video the installation would have been harder. Also the carriage bolts were sub par at best. I needed to run a tap over all of them to clean the threads otherwise the installation would have been almost impossible. Once the step bars were on the looked good and functioned well.
