Equalizer- Sway Bracket Jacket

I have them, been using them since about 2 months after we purchased the hitch system. Makes no difference in performance of preventing sway (that I can tell), but yes, they do reduce the noise. Keep the ball greased and keep all the other joints lubed, but put nothing on that spot where the bars touch the L bracket or the attached jacket and noises is reduced by "bunches!" Never grease that bracket. It's the friction there that helps control the sway.
