These are well made, quality products. The welds were flawless, clean and consistent, metal plates were nearly 1/4" thick steel. Not sure if this product will support 15,000lbs, or not, as the tractor can only lift 2700 and pull about 6000, that said, it'll never see that kind of weight anyway.As far as fit, form and finish these are quality, well-made units. Packaging was very professionally done, as well.
