well I personally have had both now and the imports didn't even last 3 weeks for me so they warenteed me a new set of US made ones. Well now my US ones have a BAD neg. arch in the front. So I'm working on getting yet another set of springs to replace those. I only have 1 week in Moab and 1 snowrun. 6 days of wheeling have made my new ones go bad. I just think I got a bad set of US made ones.
