Weight Distributing Towing


The Center Line Torsion Weight Disctribution Hitch and Active Sway Control system is the next generation in towing safety and performance.

The Center Line Torsion Weight Distribution and Sway Control System is the industry's first self centering sway control system, to provide you with complete confidence during, your towing experience. Compression cylinder action and torsion spring bars work together to distribute weight and oppose trailer sway before it begins, keeping your trailer straight and on center, giving you increased control. The Center Line system can be used in all driving and weather conditions including backing-up. The "Easy Adjust" head alignment systems allow quick and easy set-up at the time installation. The Center Line system is backed by a limited lifetime warranty for as long as you own the product (for complete warranty details visit

Advantages of Husky's Center Line Active Control Technology

Center Line Active Sway Control

  • Compression cylinder design applies counter pressure to actively control trailer sway.
  • Eliminates use of clamped friction materials.
  • Provides constant pressure to re-center the trailer behind the tow vehicle.
  • Can be used while backing up.
  • Tapered torsion spring bars help transfer weight between all axles of the two vhicles for safe towing.
  • Next Generation Patent Pending Technology.

The Center Line system overcomes many problems associated with the equalizing hitches and passive friction sway controls that have been in use for the past 30 years:

  • No more removing the sway control when backing up! The Center Line system is deisgned for your convenience.
  • No more waiting for the trailer to right itself as passing trucks, wind or road conditions cause sway. The Center Line system is self-centering.
  • You don't have to hear our system to know it's working. The Center Line system's advanced technology significantly reduces noise common with old technology systems.
