I don't think so. The shear strength of lynch pins depending on size is anywhere from 12-13k to 28K +

True, but remember that pins are rated for double shear yield. It's better than a bolt here, but some being half round do give up cross section. I was just wondering if that was original, it works but seems to me to leave some room for end user error if someone does not replace them with with equivalent.

I like the pin system on the car hauler even tough Dave does not Gives you the ability to adjust the chain length for different vehicles. I always need extra chain for my 4x4 labs bumper as the chain eyelets are up under / behind the bumper.

I also like those chain bolts Dave posted. What sucks down here are my retail resources are so limited. Ordering two speciality bolts online is not cost effective and it pains me to do it. There is one trailer place in the county. See if I can get over there tomorrow.

It also seems that while there would be some shear load on the pins most of the force would go into bending the link over in the event of that chain being yanked.

I'll clarify, the way they did that is fine. If you do it yourself you need to make sure the slot is cut cleanly and just large enough for the link to fit through. If it's a hole, the pin will bend or pull through before the chain link bends. Also, I thought the OEM would put them on leashes so someone can't put undersized fastener in for lost pins.

Sometimes I think you guys just like over complicating things for the sport of it.
While not as clean, why not just take the easy route and loop two chains through the "A" of the tonge and connect them via rated hardware? Or are we assuming the tongue triangulation is too far away or ripped off in the accident completely?

I'm not sure why you guys are dogging on quick links, some of them ARE rated and are even supplied by Reese as a product intended for towing.
A rated one:
http://www.homedepot.com/p/Lehigh-35...3S-6/100299638

You rip through two of those, and you likely rolled your truck in the process.
Or, if you REALLY want sturdy, use these: http://www.westmarine.com/webapp/wcs...classNum=50333

You can find those cheaper than west marine, but good lord, 6,500# per link should suffice.

Oh, I agree. For me I guess is the challenge is to fabricate something that looks super clean and is still as strong or stronger than the standard solutions. So yes there is some sport to it

I used the quick links on my other trailer (3/8") and I'm not against using them, but on this project I'm trying not to. My only complaint is that for any given size the quick link is rated at about half that of the chain(grade 70). I plan to use 5/16" chain so the quick link in this case is rated at 2200lbs. That's a little under the gross trailer weight but with two in the system I should be good if I go that way. Anything will be better than the 1/8" chain that came on the trailer And in addition to the lack of strength my current chains are just too short.
