Other manufacturers offer tubular arms that are like an OE replacement & advertised as 'better' because of the tubular construction. But when you're lowering one of these trucks, one of the first mods many of us do is add lowering blocks. Why not build the drop into the arm since you're building the arms anyway?? No extra expense for blocks. No extra expense for longer u-bolts. Is that all? Nope.
15" wheel guys should also see benefits because the u-bolt nuts are no longer under the bottom of the arm offering better scrub-line clearance. That's it right? Nope, still more....
Tubular arms offered before were more rigid in construction w/poly bushings. That's not necessarily optimum for a system that utilized the flex of the original I-beam construction & rubber bushings to limit bind (the more rigid construction of the tubular beam is good by itself; just not so good in this app as it will bind sooner). But, plug in a bushing that limits slop & offers better articulation & the tubular beam get's much better. The flex joint is also rebuildable & greaseable.
These are similar to NASCAR arms but w/o the harshness of the mono-ball bushing which would wear quickly (much like a heim-joint) in a true 'street driven' environment.
