Caster Arm Kits for Vehicle

Caster arms are a key suspension component used to locate the axle and maintain correct caster angle on many 4x4 suspension systems. Caster angle directly affects straight-line stability, steering return-to-centre, and overall steering confidence, particularly on lifted vehicles or 4WDs running larger tyres.

By keeping caster geometry correct, caster arms help your 4x4 track predictably on-road while maintaining control off-road.

Why Upgrade or Replace Caster Arms?

Suspension lifts and ride height changes can reduce caster angle, leading to vague steering feel, wandering at highway speeds, and reduced steering return-to-centre. Worn bushes or damaged arms can also allow unwanted axle movement, making the vehicle feel unstable under braking or through uneven terrain.

Upgrading or replacing caster arms helps restore correct caster geometry, stabilise steering response, and reduce unwanted movement under load. This is especially important for touring, towing, and off-road builds where suspension geometry needs to remain consistent across real-world conditions.
