Suspension geometry is critical for safe, predictable handling and even tyre wear—especially for lifted 4WDs. One of the most important angles is the caster angle, which directly affects straight-line stability, steering feel, and tyre life. When you lift your 4WD, the caster angle can become less positive, leading to wandering, heavy steering, and uneven tyre wear.

What Are Caster Correction Bushes?

Caster correction bushes are suspension components designed to restore or enhance your vehicle’s caster angle after a lift or to counteract handling issues. They replace the standard bushes in the suspension arms and are offset to provide the extra angle needed for correct alignment.

When Should You Use Caster Correction Bushes?

Caster correction bushes are highly recommended in the following situations:

  • After a Suspension Lift: Lifting your 4WD changes the geometry and often reduces caster angle. Correction bushes restore the optimal caster, improving stability and steering.
  • Experiencing Handling Issues: If your vehicle wanders, has poor return-to-centre, or feels unstable at higher speeds, caster correction bushes can resolve these problems.
  • To Prevent Uneven Tyre Wear: Incorrect caster can lead to accelerated or uneven tyre wear. Restoring proper caster with correction bushes helps extend tyre life.

How to Use SuperPro Caster Correction Bushes

SuperPro offers Single Offset and Double Offset caster correction bush kits to suit different levels of “pull” or alignment needs in your 4WD:

1. Correcting a Slight Pull to the Left:

Use a Single Offset Kit—fit an offset bush to the passenger side and a standard bush to the driver’s side. This helps neutralise minor left pull and improves tracking.

2. Correcting a Strong Pull to the Left:

Install the Double Offset Kit—fit one offset bush to the passenger side to increase caster and one to the driver’s side to decrease caster. This setup is ideal for vehicles with more pronounced alignment issues.

3. Maximising Handling with No Pull:

For vehicles with no pull but where enhanced performance is desired, use the Double Offset Kit on both sides. This adds positive caster to both sides, giving:

  • Improved directional stability
  • Crisper, more responsive steering
  • Better return-to-centre steering feel

Installation and Best Practices

Installing caster correction bushes typically requires removing the existing bushes and pressing in the new ones. For the best results and correct alignment, have this done by a professional or experienced suspension specialist.
