These work pretty well. Very Solid design. The other review is kind of correct about the cut being challenging. I welded them together at the correct width and parallel, so that I could hold them up with a jack in the middle to cut and grind until it was close enough. They did happen to fall in a spot on my frame that was curved up and sideways, so it was quite difficult to work out the cut prior to welding them together. I've had them in the truck now for about 3 years and they have been working great. Leaf sprung trucks are notoriously high and this was a great way to keep the truck low.
