Sway bar in the rain

i don't know and im assuming (hmmmmm) that you mean the anti sway bars?  Would be interesting to hear from someone in the know on this.  I can't see any reason not to use them ever.

Got it, friction sway bar on the trailer.

Fair enough Mike, I'll loosen it the next time it's raining.  I'm typically taking it easy in the rain anyhow.  I was just surprised that I had never heard that before.

CharlieM,

Here is quote from etailer, and when I installed my friction sway bar it came with the mentioned warning to disconnect or disable in slick conditions. I admit I have traveled in the rain with mine connected and functioning.

"The instructions included with the Curt Friction Style Sway Control System, part # 17200 state that when you are towing in wet, icy, gravel, or snow-covered roads, the sway control MUST be removed. I am only passing on the information included with the products we offer.

The reason is that the sway control can make the system too stiff when you face road conditions like those mentioned, and if traction was lost for the trailer it would push the towing vehicle and be very dangerous. It may be an inconvenience to disconnect the sway control when driving on wet roads, but this is what the manufacturer states in the warning section of the instructions."
