Just me but I don't like the way they cut through the pinch weld seam to mount the sliders.
I feel being a monocoque chassis it requires this pinch weld seam to remain intact to hold its strength.
Not saying you can't use the pinch weld to mount up sliders, I have had a length of 50x50 box section bolted to it for years.
I used the holes already present along the seam to mount it up and being I have only a 2" lift it has taken quite a few hard hits and survived.
It has also protected the pinch weld from damage, I'm sure my sills would be punched in if I didn't have it there.
Other then that I like the design and feel the it would work well without the support arms installed.
My opinion is that Steel Armadillo make the best true rock sliders for WH's and XH's

Last time I enquired they wanted $700us on top for shipping so $1359usd + import duties would have bumped them up even higher so anywhere from $2K to $2.5k aussie dollars
