Gotta fix the hop first and foremost. Gotta get full length subframes, better shocks, poly diff bushings, irs cross member and stiffer springs. Without that you'll hop like a bunny and break stuff, stronger half shafts or not.

Wheelhop is what kills the Halfshafts, not hooking. Especially if your just bolt ons. Just google the IRS RED PILL, great post helps alot.

steeda and maximum motorsports have full IRS bushing kits, a diffy girdle would stop the hop as well
