An uneven trailer load or a compromised tongue could lead to a catastrophic outcome. To help the recreational tower, the Pro Series Complete Weight Distribution Kit can be used to supplement your existing towing package, courtesy of a 2-and-5/16-inch hitch ball and trailer sway control ball. The boost in vehicle-to-trailer friction at the coupling should help mitigate the effects of sway.

Additional components include spring bars rated from 550, 750, and 1000 pounds, the hitch bar, mounting hardware, and U-bolts and chains.
