Be careful, the stock rubber lines have more "give" when they do get stretched out. the SS lines do not have that give. the weak point is where the line crimps into the banjo fitting. also make sure that at suspension compression with the wheel turned slightly that the crimp fitting won't hit the shock body.
Other than that, I agree, great product. every time I have destroyed one of their lines, I have called their customer support and they send out a new line at no charge. I have unfortunalty had to replace three so far, and they still send them out.
If you didnt use them as limiting straps, their product would not have failed?
