1. Preparation: Secure the vehicle on a flat surface, lift the front end with a jack, and support it with jack stands.
2. Remove Existing Spring: Detach the mounting brackets or bolts that hold the current spring in place. Carefully lower the old spring to avoid damage.
3. Position the New Spring: Align the RA1401 coil spring with the mounting points, ensuring correct orientation of the ends.
4. Secure Mounting: Tighten all bolts or brackets to the manufacturer’s specified torque settings. Use a torque wrench for accuracy.
5. Reassemble Components: Reinstall any removed suspension parts such as sway bars, strut housings, or control arms.
6. Final Checks: Lower the vehicle slowly, then perform a test drive to confirm proper operation and absence of abnormal noises.

Maintenance Tips

• Inspect the spring for visible damage or corrosion every 10,000 miles.
• Check mounting bolts periodically; replace any that show signs of wear.
• Avoid overloading the vehicle beyond its rated capacity to preserve spring integrity.
• Keep the suspension area clean to prevent debris from compromising the coating.
