The OE truck-arms use a rubber bushing in the front. The articulation from the stock TA's comes from the I-beam style of constuction, length, & triangulated front mounting position (allowing limited twist) w/the rubber bushings. Substitute poly bushings for the rubber & you limit deflection but increase the possibility of binding.
Make a new aftermarket TA from tubular steel construction & now you've also removed the ability to flex over the length of the TA which again increases the possibility of binding.
The tubular arms offer greater strength & rigidity. Add the pivot-joint style bushing up fromt & you end up w/precise control of the arms movement w/better articulation vs. the less than stellar rubber bushing (pivot joints yeild about 33° of articulation).

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
