Installation Tips & Best Practices

1. Lift and safely support the vehicle; remove wheels for access.

2. Remove the stock sway bars, brackets, and bushings.

3. Check and clean mounting surfaces to ensure proper alignment.

4. Install the new adjustable bars, choosing the initial stiffness settings.

5. Use the new links, brackets, and hardware included in kit—torque to spec.

6. After the first few test drives, recheck torque and alignment.

7. Adjust the bar settings (front/rear) to fine‑tune handling balance.

Pro Tip: Label your original bar settings before removal so you can revert or compare. Use anti‑seize on hardware, especially in corrosive climates, to prevent future removal issues.
