you dont actually need those things, you can remove your towbar and just use the reciever and pin just as affectively and its safer not having a shackle and piece of box section that can potentialy go flying if something lets go
Yeah, I have done that a couple off times, but i keep thinking its going to bend my pin.
I understand what you saying, but there is no room for movement with that adapter. I mean as opposed to pulling on the center of the pin that has no support, for well, 2"
I was a bit worried abt the pin so just drilled the receiver and the trailer hitch out to 20mm (21 or 22??)and bought a $15 implement pin from a tractor place. Keep the shackles out of the system I recon.
