Anyone consider Aluminum sliders? Obviously you would use a decent thick walled aluminum tube (Square or Round) and build them just like any of the normal sliders.
I was talking to my neighbor today who does a lot of aluminum custom Gas tanks for diesel trucks using the spare wheel well. (Very cool BTW.) I broached the subject with him on the idea, and honestly for the light amount of off-roading I would do anymore this may be a nice option. We could purchase some nice 1/4" wall aluminum tube from the local aluminum supplier, and then use a 1/4-3/8" L angle for mount points.
The idea being that these would be stronger than just nerf bars or step tubes, and give you a 75% solution for mild off-roading, yet save some weight.
I think the major considerations would be dissimilar metals oxidation between the frame and the L angle, or possibly the aluminum turning dull, unless they were painted or powder coated.
Has anyone ever considered it/made any?
