Overall Assessment

Customers have expressed their satisfaction with the product, praising its precise fit, quality, and ease of installation. The U-bolts are durable, well made, and boasted an ideal size for many applications. Users appreciated the additional features like being fully threaded and accompanying nyloc nuts. However, some remarked that the pack could benefit from including hardened washers. A few users noted a slight discrepancy in size but were able to adapt the product to fit their needs. The product was deemed practical, an excellent value, and a preferred choice over local alternatives. It was consistently recommended for those seeking a cost-efficient, high-quality product.

Good

The u bolts are good quality. However, the specs listed in the web site are incorrect. It list the diameter as 3 1/4 inches. The picture shows 3 inches. The actual diameter is 3 1/8 inches. I was able to modify them to work. I wish that you actually had 3 1/4 inch diameter. That is what my 9 inch ford rear end requires.

Just missed a few small details.

Used this to upgrade rear axle. Would have been nice to have hardened washers included. Kit includes nylon lock nuts, this is great for final assembly but I went and bought regular nuts for mock up since the axle will need to come in and out of my project a couple times.
