Torsion Flex Hitch


With Rubber Torsion Hitches only 10% of the trailer inertia transfers compared to 100% using a hard connection hitch giving you the ultimate control.

Ultimate Control

The tow vehicle and trailer track independently giving you greater control and added safety by reducing sway and trailer bounce.

Greatly increased braking control since all the weight on the tow vehicle and trailer is distributed evenly giving you increased positive contact when braking and maneuvering.

Safeguards Against Uncontrollable Road Conditions

Bumps, potholes, expansion joints, curves, hills, and other drivers can be a hazard, keeps you under control when confronted with these conditions.

Saves Gas and Tire Wear

The 90% smoother ride allows you to glide instead of bounce increasing gas mileage.

Saves You Money

Reduces trailer and content fatigue. Metal fatigue caused by traditional towing results in your trailer and its contents taking a beating. Products increase life and help hold value.

Arrive Alive

Reduces driver fatigue to help ensure everyone (family, friends, pets, horses, and livestock) arrives alive.
