Long arm upgrade??

In a radius arm set up when flexing, the arms are basically turning the axle housing into a torsion bar. That is why you need rubber joints at the axle end and eventually they wear out with use. With a 3 link, those rubber joints can deflect under load, leading to wheel hop and whatever. I think it's quite a bit of load for that one little bushing to handle and will wear out quickly. Plus I do not like the idea of that one little 10mm bolt holding the upper arm. If you're going to a 3 link why not maximize it's potential with a hard joint like a heim.

Another thing to consider is the "spin" I guess on the bushings as the suspension cycles. With a long arm the the bushings will see less deflection for the same amount of travel as a long arm.
 
Heres another vendor i never here mentioned:
