Hey, has been discussed before somewhere on here? Any who, yep they are good much better than the flimsy aluminium ones. Very substantial indeed. The only problem I found was fitting the dam things! the front is straight forward using the chassis bolt, but the back requires making some brackets up and I personally attached them to the rear out riggers, next to the fuel tank. The best part is when you are in ruts and you slide to the side at least you know there is something protecting your door!
