Lesjofers 4292600 Coil Spring Rear

Overview

The Lesjofers 4292600 Coil Spring Rear is a high‑performance suspension component designed for the rear axle of light commercial and passenger vehicles. Manufactured by the renowned Swedish company Lesjöfors, this coil spring delivers exceptional durability, precise load handling, and consistent ride quality across a wide range of operating conditions.

Key Features

• Material Excellence: Crafted from premium alloy steel with a proprietary heat‑treatment process that enhances tensile strength and fatigue resistance.
• Load Capacity: Rated for heavy-duty applications, supporting vehicle weights up to 3,500 kg while maintaining structural integrity over thousands of cycles.
• Precision Engineering: Tolerances within ±0.02 mm ensure uniform spring performance and compatibility with a variety of mounting systems.
• Corrosion Protection: Dual‑layer coating provides long‑lasting resistance to road salts, moisture, and industrial pollutants.
• Compatibility: Designed for use on rear axles of models such as Toyota, Peugeot, Citroën, and other OEM platforms that specify the 4292600 series.

Technical Specifications

Installation Guidelines

Proper installation is critical for optimal performance and longevity:

1. Preparation: Clean the mounting points and remove any old spring or debris.
2. Alignment: Ensure the coil spring sits centrally on the axle to avoid uneven load distribution.
3. Tightening Sequence: Use a torque wrench to apply the specified sequence: first, tighten all mounting bolts to 30 Nm; then perform a second pass at 45 Nm after the spring is fully seated.
4. Inspection: Check for any visible defects such as cracks or excessive wear before final tightening.

Performance Benefits

• Ride Comfort: The controlled spring rate absorbs road irregularities, reducing vibration transmitted to the cabin.
• Handling Stability: Consistent rear suspension geometry maintains tire contact patches during cornering and braking.
• Durability: High‑strength alloy steel resists fatigue, extending service life even under heavy load cycles.
• Maintenance Reduction: Corrosion protection minimizes the need for frequent inspections or replacements in harsh environments.

Applications

The Lesjofers 4292600 Coil Spring Rear is engineered to fit a broad spectrum of vehicles, including but not limited to:

• Light Commercial Vehicles: Vans and pickups that require robust rear suspension.
• Passenger Cars: Models from Toyota, Peugeot, Citroën, and other OEMs with matching specifications.
• Specialty Applications: Off‑road or industrial vehicles where load capacity and durability are paramount.

Quality Assurance

Lesjöfors adheres to strict quality control protocols. Each coil spring undergoes:

• Dimensional inspection using laser measurement systems.
• Hardness testing (Rockwell C) to verify heat‑treatment consistency.
• Fatigue testing under simulated load cycles to ensure long‑term reliability.

Maintenance Tips

To preserve the integrity of the Lesjofers 4292600 Coil Spring Rear:

1. Inspect annually for signs of corrosion or deformation.
2. Avoid overloading beyond the specified weight limit.
3. Keep mounting bolts clean and free from rust; replace if corroded.
4. Store in a dry environment when not installed to prevent premature oxidation.

Conclusion

The Lesjofers 4292600 Coil Spring Rear exemplifies engineering excellence, combining robust material properties with precise manufacturing tolerances. Its proven performance across diverse vehicle platforms makes it a reliable choice for anyone seeking superior rear suspension quality.
