Just posting this as an FYI for people. Last ride I cooked my brakes on my 2019 Aro SX. Timbersled only sells the entire caliper, and all I need is the seal kit. After a lot of time spent with Wilwood trying to figure out what I have we were able to identify it. I wanted to post it here for others:
