Wanted to share what I found twice now on my arched A arms from Super ATV. I found the threaded shaft of the pivot blocks to be a weak point. Both bent in the same spot (at different times), the rear A arm toward the front of the machine. I had both replaced under their lifetime warranty no problem at all!! Also found out they've upgraded the steel used on the A arms. This isn't something that I would have found unless I was readjusting my camber. Those of you with these might want to check. An easy sign to show any damage is to look at the nut on the pivot block and make sure its setting flush agaist the A arm. All super ATV will ask is a pic of the damage and they'll take care of it!!!! Great customer service!!!!!
