Installation & Compatibility

The Lesjöfors 4272932 is engineered for direct replacement of the OEM coil spring. It fits the standard mounting points and dimensions used in the rear suspension assembly, allowing for straightforward installation without the need for additional adapters or modifications.

• Mounting: Uses the same bolt pattern as the original part.
• Length & Diameter: Matches OEM specifications to avoid clearance issues.
• Installation Steps:
  1. Remove the existing coil spring using a suitable spring compressor or puller.
  2. Align the new Lesjöfors spring with the mounting brackets.
  3. Screw in place, ensuring even tightening to maintain proper alignment.
  4. Reinstall any associated components (e.g., sway bar links) and perform a final torque check.

Performance Characteristics

The spring delivers consistent performance across a wide range of operating conditions:

• Load Capacity: Designed to handle typical passenger and cargo loads without excessive sag.
• Ride Comfort: Provides a balanced feel, reducing harshness over uneven road surfaces.
• Handling Stability: Maintains vehicle alignment and steering response during cornering.
• Durability: Heat treatment and material selection reduce the likelihood of fatigue failure over time.

Quality Assurance & Standards

Lesjöfors adheres to stringent manufacturing standards, ensuring each spring meets the following criteria:

• ISO 9001 Certification: Guarantees quality management processes.
• Compliance with OEM Specifications: Meets or exceeds original equipment manufacturer requirements.
• Rigorous Testing: Includes static load tests, fatigue cycling, and environmental exposure assessments.

Maintenance & Longevity Tips

While the spring itself requires minimal maintenance, overall suspension health can be preserved by following these guidelines:

• Inspect for visible damage or wear on mounting points and bushings regularly.
• Keep the suspension area clean to prevent corrosion.
• Replace any worn shock absorbers or struts in conjunction with spring installation for optimal performance.

Conclusion

The Lesjöfors 4272932 Coil Spring Rear is a reliable, high‑quality component that delivers OEM‑level performance and durability. Its precise engineering, robust material construction, and straightforward installation make it an excellent choice for vehicle owners seeking to maintain or restore the original ride quality and handling characteristics of their rear suspension system.
