Increasing anti-sway-bar diameter or adding a rear Hellwig sway bar can greatly improve handling and stability, whether in a sports car, motorhome or heavily loaded truck. In a lower or raised vehicle, anti-sway bars can also compensate for dynamic handling changes. Hellwig anti-sway bars use 4140 chrome-moly spring grade steel, and bar are entirely heat-formed and coined as one piece, for strength and resistance to torsion.


Reduce Body Roll and Improve Overall Control
reduce body roll with Hellwig anti-sway-bar

Body roll is reduced by the torsional effect of Hellwig Anti-Sway Bars, which transfer pressure from outboard wheels to inboard wheels in a turn. That means weight is more evenly distributed to all four wheels, helping to keep your vehicle more level with the road, and improving you overall control.



Q. What's the difference between Hellwig's Anti-Sway bar and the competition?

A. The biggest difference is that Hellwig's anti-sway bars are made entirely of 4140 chrome-moly spring steel. They use only high-quality heat-treated material. All the Hellwig sway bars are heat-treated, making them some of the strongest on the market; most of the competition just cold-form their sway bars. They also include heat-treated spring-steel mounting brackets with heavy-duty end links and polyurethane bushings in every kit.
