These bushings last a good amount of time. Probably the best poly bushings out there, only reason I needed to order new ones was my bolt had siezed and I needed to cut the the bushing, sleeve, and bolt to get the arm out. My advice is to put anti-sieze between the sleeve and the bolt to avoid the problem I had. I like using ballistic fab parts and will probably use the JJ rod ends when I redo my build.
