Why Can't a Trailer be Backed Up when Using Friction Bar Sway Control  

Question:

Weight distribution systems that use friction bar sway control such as # PS49901 do not allow backing up a trailer unless it is in a straight line. The issue is that the forces applied to the friction bar are different in reverse (there is physics that explains it but it's over my head) and it can damage the friction bar and/or the trailer. You can disengage the friction bar and then it would be fine to back up while turning.

For a similarly rated system that has built-in sway control and will not have reverse restrictions I recommend Fastway e2 system # FA94-00-0600. The only other item needed is a properly sized ball such as # A-90 for a 2 inch or # 19286 for a 2-5/16 inch.
