These are forged not cast, and according to a tremendous amount of research, are stronger and will withstand much more wear and tear. And since they are on my wheels. They went on as easy as the instructions said and I couldn't be more pleased with the look of my Jeep as well. I recommend this brand to anyone looking for this type of product.
