12K Equal-i-zer® 4-point Sway Control™ Hitch

Catalog Item # 47628

Unique two-in-one design combines weight distribution with sway control, all in one easy-to-hook-up system that works on any trailer.

  • Combines weight distribution and sway control in one simple design
  • Four positive friction areas combat sway
  • Innovative rigid sway control brackets fit trailer frames up to 6” tall
  • Brackets are designed for flexible placement on trailer frame without interfering with tongue jacks, propane tanks or other accessories
  • Works on any type trailer including travel trailer, boat trailer, cargo trailer and more
  • Works with boat trailer surge brakes, unlike other weight distribution and sway control systems

How It Works Downward pressure from the trailer tongue and upward pressure on the spring arms activates the rotational friction sway control. The spring arms link the rotational sway control to the sway control brackets and distribute the weight of the trailer tongue. The rigidity of the sway control brackets allows the dual rotational friction sway control to hold the trailer in line behind the tow vehicle.
