Control Arm & Radius Arm Kits for Vehicle

Control and radius arm kits are engineered to upgrade the core structural elements that define suspension precision, steering stability and overall handling feel. By replacing flexible factory components with stronger, better aligned performance arms, these kits restore correct geometry under load and eliminate unwanted movement that can dull steering response or reduce grip. Each Whiteline kit includes 2 control arms and 2 radius arms, delivering a complete front end solution that transforms how the vehicle behaves on the road.

With improved alignment stability, enhanced rigidity and more consistent suspension behaviour, Whiteline control and radius arm kits deliver sharper turn in, better mid corner support and a more planted, predictable feel. Precision engineering, smart design and extensive real world testing ensure every kit provides a noticeable improvement in vehicle balance, confidence and connection. Drivers feel more in control, more engaged and more rewarded every time they turn the wheel.

Why Upgrade Suspension

Factory suspension components often prioritise ride comfort rather than performance, which can lead to unwanted flex, geometry change and reduced stability when the vehicle is pushed harder. Upgraded arms reduce squat, dive and unwanted sway by maintaining correct alignment angles under braking, acceleration and cornering.

More consistent geometry means sharper, more predictable handling that inspires confidence in both everyday commuting and spirited weekend driving. Reduced deflection increases tyre contact with the road, improving grip and stability. The result is a vehicle that responds more cleanly to driver input and feels more stable across a wide range of driving conditions.
