In searching for an inexpensive set of side steps I decided on the SS 3" bars sold under the Ionic brand. The are basically the house brand of AutoCustoms/running board world, etc. (lots of branded websites, they are all really the same company). They are actually made by Steelcraft.
Anyway, they are advertised as 304 SS with 90 degree bends and body bolt mount which is a very solid and clean mounting method. So, with an $188 price they seemed like the best, low cost option.
Well. They showed up yesterday and instead of 90 degree ends that mount to the body bolts they have 45 degree ends and use the factory rocker panel mounting brackets. It's the same part number bit it now says it works on '07 - '14 extended/double cab Silverado/Sierra 1500's. After a call to Auto Customs and eventually Steelcraft it turns out there is some reason the body bolt mounting system is not compatible wit h the 2014's even though they originally had them mounted, photographed and instructions printed showing that method. I'm waiting for a call back from Steelcrafts engineer but he was at SEMA all week so I expect a call back next week.
So, I just wanted to let everyone know that it looks like rocker mount is the only type of boards appropriate for the 2014's. Don't be mislead by some websites.
