With all these companies building SAS stuff, Id go that route before I would swap to 3/4 ton stuff. I did an SAS years ago in a storage unit, once everything was unbolted, drilled some holes and bolted the SAS stuff on. But its' not cheap, that is for sure. I have over a grand in the brackets, crossover, and shackle flip. But it's insanely overbuilt, so will be good for awhile.
