FREQUENTLY ASKED QUESTIONS
A caravan sway bar reduces trailer sway and body roll while towing.

Griptech’s Tow-It Series Sway Bars are precision-engineered for serious towing safety.

Tow-It Series Sway Bars are tuned for Sway resistance, not stiffness. Independant suspension is without doubt the best way to ensure stability on rough terrain, however if you spend allot of time on highways before arriving at the dirt road, a sway bar kit will get you there with more comfort, safety and confidence. If you are researching how to stop trailer sway, caravan wobble or lean you will know what we mean.

- Sway bar = reduces sway and roll
- Weight Distribution Hitch = distributes weight more evenly across axles
