Are these legal as a subtitute/replacement?

My TT fully loaded is 6817#, I'm not at home to check my TT but if I remember correctly the metal tag on my chains says 7,900# and break away is 1,790# .

I see those cables are rated at 8000 pounds. Do you know what your safety chains are rated for? What does your camper weigh?

I used those cables for towing my car behind the motorhome, so 8000 pounds was plenty.

What is GVWR of trailer?

Class 1----------2000#
Class 2----------3500#
Class 3----------5000#
Class 4 - The strength rating of each length of safety chain or its equivalent and its attachments shall be equal to or exceed in minimum breaking force the GVWR of the trailer
