Whiteline KCA439 Roll Center Correction Ball Joint Kit for 2005-2010 Ford Mustang

Fits 2005-2010 Ford Mustang Base, GT, Bullitt, Shelby GT, and Shelby GT500 models.

Lowering an S197 Mustang often compromises its suspension geometry by dropping the roll center, which leads to increased body roll and reduced front-end grip. The Whiteline KCA439 Roll Center Correction kit is engineered specifically to restore proper geometry on lowered vehicles. By raising the front roll center, this kit increases roll resistance and reduces outside wheel compression during hard cornering, ensuring a more consistent tire contact patch and higher cornering speeds.

This kit features three adjustment settings, allowing for precision geometry tuning based on your specific ride height. Each component is finished with a protective plating designed to withstand harsh road conditions and resist corrosion. This kit also helps optimize toe alignment to rectify uneven tire wear and reduce inherent understeer or oversteer behavior.
