The majority of the time we converted to use hiem joints. Havent seen to many TRE's breaking but mostly studs sheering/tearing out. What needs to happen instead of all this 5/6 stud BS is do like companys have been doing with dana 60 knuckles/arms and start adding keyways to help with the sheering forces.
Idealy if i was going to run a toyota axle i would convert to D44 ARP studs/cones and machine my knuckles and arms for a keyway.
As for the 4x4labs arms i think ive only ever seen one pair so im not really in a position to base an opinion on them as i really dont remember much about them. Plus their website is down so i cant look :\
