They're prob. overkill for your setup, I built them for serious abuse for a heavier rail.  They're about 34" long from center of mount to center of bearing carrier, 14-3/4" from center of heim to center of heim,  and weigh about 48 pounds each.....I sell them for $1,500.00

48 pounds + wheel and carrier= one mighty amount of unsprung weight.

I would only consider half of the trailing arm as unsprung...........  Does that help?  ;D ;D ;D

NO since almost all of that arm is unsprung weight.IMO it does not qualify as 1/2 and 1/2.The mass is at the end of the arm so it is almost totally unsprung weight.

I need to weigh both ends and see what's unsprung weight. The 48 pounds is shipping weight, so they are a little less, but still heavy...

To do so you need to support one end at it's pivot point and put the other on the scale. do this for the heim pivot points and the axle pivot point just like we do to balance connecting rods to do the weighing correctly.

Inside and outside need to be triangulated all the way to the heim, but this is where you'll notice it bending first..

I think you'll hate the squeeking that the PU will do as soon as the grease goes away which IMO will happen quite quickly with long travel. Yes there's a zerk but you'll need to grease it regularly. Otherwise I don't like the welded stud to the ferrule. Probably fine but I just don't like it. Why are you considering using it?
