Yes you would probably notice a good improvement using a Dual Cam sway system over the twin friction bars. I said probably because I have not towed with two friction bars - only one. I noticed a huge improvement when I switched to the Dual Cam.
Yes the Dual Cam will probably fit your present EZ Lift bars. Others on the forum have done it. You may have do do a bit of filing or grinding on the ends of the bars or perhaps drilling out a hole or two but it can be done, and is worth the effort.
I am interested in the dual cam system because I actually pull my camper behind a 16' ATV trailer. I eventually want to get two complete setups, but finances are restricting me to buy one at a time. Which one should I install it on first. The ATV trailer directly behind the truck or the camper behind that?
I pulled a 31' Holiday Rambler Presidential for 10 years with a friction sway control and didn't think I could get any better control. Then I went to the dual cam and a 34' Airstream, for four years and what a difference the dual cam made. Now I think I have the best, see sig.
