Just thought I'd bring this back to life and give an update after 7 months with the system.
Since I installed the SS, I have driven approximately 17K miles. Admittedly, I haven't done a ton of offroading, but I have had a couple offroad incidents that hammered the froint suspension pretty good. So far I have not had a single problem with the system. I tightened the idler arm once and I grease the centerlink ends once in awhile, but other than that, there has been nothing to fix and I don't see anything that would appear to be worn or defective in anyway.
Two thumbs up to the Calmini SS at this point!
