Haven't hauled anything with them yet but they seem hearty and strong. Installation instructions were spot on! Had them both installed in under 10 mins.

A great product that makes attaching travel trailer chains on my F350 much easier. Highly recommend. And fast efficient shipping too!

Zero installation instructions. Looks like a great product, I wish I could install it.
We have videos and instructions on the Autohauler Supply Website.

I was worried about installation on my truck with little leverage being tough but a little grease and a dozen or so whacks with the household hammer and they were on secure. Nice product!

Like most people, had to work a little to get them on, but man what a time saver. Hooking camper up to F250 is SO much easier! Recommended!
