Center Line® Towing System
Weight Distribution, Sway Control and Trailer Centering In One
You need a weight distribution system to level your load (or to properly equip your tow vehicle), but you also need to handle cross winds, truck traffic, ruts and curves that can contribute to trailer sway. The HUSKY CENTER LINE™ Towing System addresses both of these concerns with the added benefit of returning the trailer to center for you.
The industry’s first self-centering sway control system employs compression cylinder technology to counteract trailer sway before it begins. Keeping the load level and the trailer straight in all driving conditions is what the CENTER LINE™ is all about.

- Compression cylinder creates resistance to minimize trailer sway
- Lateral movement loads compression cylinder springs to return
trailer to center - Load matched tapered torsion bars ensure proper weight distribution setup

Active Sway Control 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 designed 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.

Key points of the CENTER LINE hitch
- The “Easy Adjust” head alignment systems allow quick and
easy installation set-up. - Compression cylinder creates resistance to sway.
- Cam-style trunnions activate the compression cylinders to
control sway. - Tapered torsion spring bar provides proper weight distribution.
- Streamlined sturdy bracket design instead of chains for easy,
no-drill set-up.
