Roadmaster or Hellwig

I have a stock sway bar on the front, and added a Bigwig on the back. I believe it has 3 settings. I had to call their cust. support once to get the best setting to use. On a Sunday afternoon, just before dinner I had a tech. on the first ring. Amazing,....knew his stuff too.
I am very happy with the product,....AND the service. I don't know anything about Roadmaster.
