As a paralever newb still learning the perils and pitfalls of paralever use, I'd be concerned by the fact that these shortened torque arms severely change the angles of the U-joints in relation to one another. These u joints are phased so that they cancel each others' vibrations when they are both operating at similar angles. If one joint is nearly straight and the other is at an angle, then that will result in vibration and axial loading that was not intended by whoever designed this abomination of a driveline. I've been reading up way too much on drivelines trying to eliminate a nasty vibration on my pickup with a 2 piece shaft w/ carrier bearing getting pinion angle and midshaft angle out of the trans within a degree of right. It's been interesting.
