40s on 44s isn't risky. Rather it is a certain, 100% guaranteed more expensive way to go because if it is off roaded, you will either upgrade to tons or go back to 37s. I destroyed 2 rear 44s trying to "save money" by not upgrading to a 60.
A crate rear 60 is about $3500. It doesn't make sense to put any money in a rear Rubi 44 when you can sell it for about $1500 before you bend it, break the locker, bend the rear axle shafts, and/or blow the rear ring and pinion.
40s mean upgraded driveshafts, hydro assist, a super wide front axle or increased steering radius.
Now, it is on a 4.5" long arm with Currie RJ 60s and no body lift.
