Too many of the coil spring trucks are dropped varying amounts and do hook up without altering pinion angle for this to be a cure all.
Worn out bushings in the trailing arms as well as ineffective shocks are better places to spend time/energy while the housing is out getting gears.

Anytime I've changed gears.. going to a steeper set 3.73/4.11/etc
it only made a traction issue worse.. 2 tires (posi) with a pinion angle that never loads the tires. will just spin, like the peg leg.. only now it's slides sideways.. looks cool, but doesn't get you moving
In a truck with nothing over the rear tires.. the pinion angle and instant center means EVERYTHING..
Could not ask for longer ladders to leverage off of.. but you need the correct settings.. the lowering it.. did it no favors here.. the pinion angle and long arm mounting points need to change..
Posi will help.. but not where I'd go first.
