Equalizer now offers a hard rubber pad to place on the L bracket under the sway bar. Reduces noises greatly, not all, but a lot. Equalizer says that it does increase sway a little bit because of the small amount of friction that is reduced by the pads but DW and I just returned from 2,000 mile trip and I myself really didn't feel any loss of sway control. I really like these pads because they do reduce noise. DW is happy about that. Cost was if I remember correctly was $15.00 plus shipping. Was with it for me.
