Love Jon's content, I got a chance to meet up with him when he was in Vegas, small cameo in two of his videos. One of the Monache Meadows ones and I think I showed up in the year recap one during the Lake Mead portion. Super friendly dude.
I will say, Traxda customer service is on point too! Truxxx as well but they do not make a 3.5" kit. I did want to mention, readylift has a 2.5" lift kit now too.
