Trailing arm opinions

Hi all. I have a 2013 XP900 Jaggex X edition. I was out riding this past weekend, and while negotiating a tight section of trail (going very slowly 5-10mph in L), I apparently came in ckntact with a stump. Thought all was fine until I got home, and you can see the rear passenger tire is slightly towing outward. I can see no bend in the trailing arm, but can see with a straight edge it is bent ever so slightly. Was already told Polaris will not warranty this. So now its time for a new trailing arm, and I figure might as well do an upgrade. Which aftermarket trailing arms have you used? And how have they been working out?
