As many know there have been plenty of companies out there that copied the Skinz Airframe running boards. All of which are being sold cheaper than the Skinz boards so I took it upon myself to buy a set to see why. Below you can see the cut a way of the two different boards, Skinz Airframes in white and Brand “X” in black.

Wall thickness on the outside tube:
Skinz boards = .255”
Brand “X” = .135”
We all know how important the outside rail is since that is the main support for the boards on a stock sled. Brand "X" is only a little more than 1/2 the thickness of the Skinz board.
Now let’s look at the cutaway of the foot tubes.
Brand "X"

Skinz

Skinz boards = .05” wall thickness
Brand X = .12” wall thickness
Skinz board is machined to accept each and every foot tube at the outside rail. The foot tube slides into the .25” wall tube and is welded.
Brand “X”, the foot tubes are coped and welded which is not nearly as strong as the Skinz set up.
Brand “X” boards are nicely constructed but you get what you pay for and the average customer obviously buys the cheaper pair because they claim to be “as strong” as the Skinz boards for less. Now if it were me, and I was cutting my running boards off I certainly wouldn't want to cut corners on what I put in their place. Just because they look similar on the outside doesn't mean they’re the same inside.
Hope this helps you make a better purchase.
