Radius Arms

Radius arms play a crucial role in controlling longitudinal wheel movement and stabilising suspension behaviour under braking, acceleration and cornering. By managing how the front suspension locates and pivots, radius arms help maintain correct wheel alignment, reduce unwanted fore and aft movement and keep the vehicle stable and predictable. Whiteline radius arms are engineered to increase rigidity, refine geometry and deliver a more confident, responsive driving feel.

With stronger construction, precision bushings and geometry focused design, Whiteline radius arms transform steering stability, improve braking confidence and create a more planted feel on the road. Extensive real world testing and performance driven engineering ensure every component delivers measurable improvements to handling accuracy, grip and overall vehicle balance. The result is a sharper, more composed driving experience that enhances both everyday and spirited driving.

Why Upgrade Suspension

Factory suspension often prioritises comfort over dynamic precision, which can lead to unwanted flex and alignment change when the vehicle is under load. Upgrading radius arms helps reduce squat, dive and unstable weight transfer, creating a more controlled and predictable chassis.

Improved rigidity reduces deflection and maintains better geometry throughout the suspension’s movement. This means increased grip, more consistent tyre contact and sharper, more dependable handling. Whether commuting or pushing harder on the weekend, upgraded radius arms bring confidence, stability and enhanced feedback to every corner.

Why Choose Whiteline

Whiteline radius arms are built on a foundation of engineering expertise, precision manufacturing and extensive durability testing. High strength materials and advanced polyurethane ensure long term stability, consistent alignment control and reduced flex even in demanding conditions.

Each arm is designed for specific vehicle platforms to deliver the most effective geometry correction and handling improvement. Whiteline’s reputation for sharper steering, improved grip and enhanced stability makes these upgrades trusted worldwide by enthusiasts and performance drivers.
