x2 on hondavalk comment,
Sorry to hear you had these issues. Just my opinion,but they should have never put 1K bars on a that trailer.
Just for food for thought here, if you're staying with EazyLift..
Depending on your relationship and distance from the dealer, I'd go back and talk to the manager about what they did and discuss crediting you back your cost for the bars and install the 1400 set.
Do a couple test tows with the new bars and see if it helps.
I'm a fan of the friction sway bars on that hitch, but just my experience.
I'm using the ProPride setup and could not be happier. Pricey, but well worth the investment for us. Was around $2K and I installed them on a Saturday afternoon myself.
Hensley has a great reputation, but it's up there in price, like another grand.
