This case has upgraded caps and the billet adjusters,this is not the std yukon case,its something Cass had made,something about ford 9" 3.25 caps machined,he could tell more.Cass has always dealt straight so I'm trusting this will be good.I've run 2 seasons on the stock case no issues,going to pull it and keep for spare plus get to take a better look at it after 2 seasons,I figure i'm getting border line 1.42 60' 3350lbs
