Essential for lowered vehicles, the Whiteline Roll-Center and Bump-Steer Correction Kit is engineered to restore suspension geometry after ride height adjustments. When a vehicle is lowered, the angle of the front control arms often shifts, moving the roll center further away from the center of gravity and increasing body roll. This kit uses specially engineered ball joints and tie rod ends to raise the front roll center, significantly increasing front roll resistance and reducing suspension compression on the outside wheel during high-load cornering.

By correcting the geometry, this kit improves weight distribution across the tire contact patch, enhancing front-end grip and steering precision. The included tie rod ends also help mitigate bump steer—unwanted toe changes that occur as the suspension moves through its travel—ensuring predictable handling on both the street and the track.

• Replaces worn OE ball joints and tie rod ends with geometry-corrected components
• Restores front roll-center height on lowered vehicles
• Reduces body roll and improves tire contact patch under load
• Improves steering response and handling characteristics

The Whiteline Front Roll-Center and Bump-Steer Correction Service Kit is an essential upgrade for lowered vehicles to restore proper suspension geometry. Lowering a vehicle often pushes the front roll center below the ground line, increasing body roll and reducing steering precision. This kit uses specially engineered ball joints and tie rod ends to raise the front roll center, significantly increasing front roll resistance and reducing suspension compression on the outside wheel during cornering.

By optimizing the roll center, the KCA313-BJ kit ensures more even weight distribution and maintains a consistent tire contact patch. This results in sharper steering response, reduced bump steer, and improved front-end grip for higher cornering speeds and better overall handling characteristics.

• Roll-Center Correction: Specifically engineered to raise the roll center height on lowered vehicles.
• Bump-Steer Reduction: Optimizes steering geometry to maintain alignment settings during suspension travel.
• Handling Performance: Increases front-end grip and reduces body roll for flatter cornering.
