I had them on my truck. With a heavy bumper and winch, they are a good addition, and much better than the more common thicker 26mm bars. They shine the best if you like to drive fast over rough roads in that they don't bottom out as easy with all the weight. However, you'll lose out on articulation a tiny bit.

Also, they don't give you any lift. The only thing that gives you lift is where you adjust the torsion bars. And it doesn't matter whether they are stock or not. The idea that thicker bars give lift or are stronger is a myth made up up to help sell them.

All thicker bars do is increase the spring rate of the front suspension, just like adding leafs to the rear springs.
