I got these to replace my tired, aging stock leaf springs. The old ones had me rubbing my tires on bumps when riding with another person. They've only been on for a few days but so far I have yet rub my tires on the speed bumps. They're a pain to install but with enough time and patience there shouldn't be any major issues. It's nothing that can't be done over a weekend. I only wish the ride height would increase more than just an inch above my old springs.
