3” receivers use a 5/8 pin too.
What needs to change?
With shear on a 5/8 Gr 8 bolt/pin being about 27,000 lbs and hitch pins being in double shear, even with a 100% or a 2:1 factor of safety, a 5/8” pin is still good for 27klbs, or 54k ultimate strength.
Short of being stopped and a semi truck rear ending your trailer at highway speeds, you can’t put 54,000lbs on a pickup truck hitch pin, even towing at the upper limits of what the truck will do.
So I’m not sure why it would need to change.
Now, for all the fools who use the adapters and tow heavy, that is not good.
As soon as you slide in one of those adapters, you weaken the hitch pin considerably as it is now also in bending.
Aside from the occasional light duty use, don’t use adapters.
Get the right size hitch shank.
When you say adapters, are you talking about the reducer sleeve that comes with the truck from the factory to reduce from 2.5 to 2 inch?
