Hellwig sway bars offer quick bolt on installation that are engineered to perform. An immediate improvement will be felt when you drive through the first corner with a Hellwig sway bar installed. Though most vehicles come equipped with factory installed sway bars, they are often insufficient for today?s load and tow demands. Hellwig sway bars feature larger than stock diameters and precision engineered components to optimize handling and reduce body roll.

- Camber and caster adjustability allows for precise wheel alignment
- ICON double adjuster sleeves allow for on-vehicle adjustment
- Vehicle specific taper pin provides OE-like fitment
- PTFE Lined 7/8” FK Rod Ends for improved response
- Built in o-ring sealed dust cover cap
- These upper control arms feature ICON's patented Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint.
