Commentary on Mopar XHD springs.

Of course I can't know what others are using, but my XHD 340 replacements are asymmetrical (different number and length of leaves). Mopar originally did that to counteract torque reaction and plant the right rear tire. That alone can and did cause the rear of the car to sit uneven in my case. A simple torsion bar adjustment leveled the car side to side and raised the front up enough to give the same tire to fender lip gap all the way around alleviating any suggestion of the stink bug phenomenon.
