Installation Overview

The installation process for the Lesjöfors 4056839 Coil Spring Front follows standard OEM procedures. Below is a concise guide to ensure correct fitment:

1. Preparation: Secure the vehicle on a lift or jack stands, and remove the front wheel assembly.
2. Remove Existing Springs: Detach the current coil springs by loosening the mounting bolts. Carefully lower the spring to avoid damage.
3. Mount New Spring: Position the Lesjöfors coil spring onto the mounting brackets, aligning it with the original bolt holes.
4. Tighten Bolts: Use a torque wrench to tighten the mounting bolts to the manufacturer’s specified torque (typically 120–140 Nm, depending on vehicle).
5. Reinstall Wheel Assembly: Reattach the wheel hub, tire, and wheel. Verify that all components are securely fastened.
6. Test Ride: Conduct a short test drive to confirm proper operation, checking for any abnormal noises or handling issues.

Performance Benefits

• Enhanced Handling: The precise spring rate improves cornering grip and reduces body roll, providing drivers with confident steering response.
• Improved Ride Comfort: By efficiently absorbing road bumps, the coil spring minimizes vibration transmission to the cabin, resulting in a smoother ride.
• Long-Term Durability: High‑strength alloy steel resists fatigue and wear, ensuring consistent performance over thousands of miles.
• Consistent Load Capacity: Maintains vehicle geometry under varying load conditions, preserving suspension alignment and tire contact patches.
