Whiteline Anti-Lift Kit (ALK) – Front Control Arm Rear Bushing Upgrade (KCA428 / KCA465)
Upgrade your front-end grip, steering response, and overall handling with the Whiteline Anti-Lift Kit (ALK) — designed to improve traction and reduce understeer on performance and street builds.
What does it do?
Whiteline Anti-Lift Kits replace the rear control arm bushings with a performance housing and low-compliance bushings, changing suspension geometry and stiffness.
Key benefits:
- ✅ Improves traction under acceleration
- ✅ Reduces understeer
- ✅ Sharper turn-in response
- ✅ More consistent alignment under load
- ✅ Increased front-end grip in corners
The kit works by:
- Increasing positive caster (~+0.5°)
- Reducing bushing flex and “wind-back”
- Improving how the tyre stays loaded during acceleration and cornering
It also modifies suspension geometry (instant centre), allowing the front suspension to work more effectively and maintain better tyre contact with the road, especially under power
👉 Result: More grip, better steering feel, and a more planted front end
Kit Features
- Performance alloy housings

Why upgrade? (simple version for customers)
Factory bushings are soft and designed for comfort.
This kit replaces them with performance parts that:
- Keep your suspension geometry stable
- Put more power down through the front wheels
- Make the car feel sharper, tighter, and more responsive
