I’ve had mine 15 months and no issues. I initially had creaking type noises but that was from the clips being too tight that keep the leaves stacked neatly. Since I loosened those there’s been no issue at all. I really like them.Potentially interested in these as well. How have they held up thus far? Any rust creeping in or major squeaks? It appears a company has finally figured out the right bushing setup for aftermarket leaf springs so I'm hopeful.
