Re: Will shackle flip affect towing capacity?

Just like a shackle flip. I haul with a shackle flip on my F-350 all the time and I'm going to bet it's more weight than 90% of the people on this truck board haul. 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.
Like I said,others will say they don't effect towing. I'm just saying I wouldn't. I just don't like the idea. Let me ask this,why do people do shackle flips? For off road they give better articulation and smoother ride. Well,where all that matters I won't be towing or hauling a heavy load,most likely. A heavy load smooths out a ride,right? That takes care of the ride. Articulation? I'm not towing anything where that matters and I sure think anyone who does will be putting those flip brackets to the test. That's just my opinion and how I would build something for towing. I generally build trucks for specific uses...fun play toys or work trucks,because I need my work truck to make a living. I can't break it up over the weekend,so that's where I'm coming from.
