Question Sway bar help for dummies

I just purchased and will pick up a 74 sovereign next week and do not know much about sway bars. From this picture, can anyone tell me what I will need to purchase to make it work? It looks like two bars are connected to chains at the tongue. I'll be towing with a MB GL450. The previous owner has no clue about trailering and does not know how to use it either.

Thank you!

What exact tow vehicle will you be using?

Different rating hitches match the trailer to the tow vehicle.

I forgot to mention one more thing. I have done some research and figured out that it is a weight distribution system. My truck has an automatic levelling feature which is part of the 4MATIC air suspension.

You cannot use an automatic leveling system with a load equalizing hitch, as that system defeats the purpose of the hitch.

Thanks Andy: That's what I had suspected. I am glad I didn't buy a new hitch setup for the WDH.

As I understand it, only if there is provision to over-ride the system while towing.

Our 3/4 Suburban does not have the auto-leveling function that the 1/2 ton's do when equipped with the AutoRide option. GM realized a lot more of the 3/4's were destined to be dedicated TV and it would be more difficult to adapt the system for WD applications.

I do know that some here tow with the system, maybe they can chime in on their experiences.

Have you weighed the trailer or know the actual weight?

There is only ONE WAY, none other.

You must defeat the auto leveling system, so that it cannot activate, and drop the air pressure to minimum.

Anything short of that will defeat the purpose of the load equalizing hitch, no if's, and's or but's. NO EXCEPTIONS.
