Notice

1. All modifications must be installed by licensed mechanics and in compliance with your local modification regulations.
2. Please ensure all components are tightened with correct torque specifications (which can be found in the vehicle service manual)before and after installation. Any loose nuts, bolts, or locks will cause noise. Do check and tighten before serious problems happen. 
3. Impact wrench is prohibited during the installation, it will loosen or damage the product.
4. Examine the clearance between tires and suspension. ( The minimum clearance should be 4mm, otherwise, you need to add wheel spacers. Caution: It is not sufficient with torsion beam trailing arm axles)
5. We suggest regular maintenance for the coil-over, spray with some WD40 every 3-4 months will keep it smooth and clean, which helps to extend the lifetime.
