Will shackle flip affect towing capacity?

On and off road, and these have been on there for 60,000 miles. 40,000 of those have had a heavy load on the truck or in it. We're talking a hay trailer with 6-8 round bales and a trailer that weighs 5500lbs empty. And this truck is lifted roughly 4" and has 33's. It weighs 7400lbs with a 1/4 tank of fuel and no fat guy in it. I also have sway bars front and rear, so she handles pretty well with a trailer on. I wouldn't be worried with a shackle flip and a small lift to tow.

Thanks, i wasn't planning on going any higher than 4" inches and a set of 285/75r16 (load range D) tires. Probably won't see much hay, just the occasional gooseneck with a car or the mud truck on it.
