Very easy to fit and durable. I've had them for a couple of months now and go off-road with a 7000lb trailer with no issues. The extra stability was immediately noticeable. I was worried because they weren't a "hub", but they work great! I had to trim the bike a bit but it was worth it. Not only does my Tahoe drive better, it feels more like a 4WD and is just the old MEAN. I am very satisfied with this product.
