The following is an image Jacob sent me from the factory. Note how the threaded end is ground to fit into the lift arm. Also note the angle the torsion bar makes.
My old torsion bars remained vertical but these new ones have a lot more tension, even with the adjustment backed right off.
Bill, I see no purpose to the threads. All I can figure is that the supplier makes the rods like that, and TM puts the bends in.
(Jacob has an iphone, so guess how the picture orients itself. )
