LesjÒ-fors 4259249 Suspension Spring

The LesjÒ-fors 4259249 suspension spring is a high‑performance, OEM‑grade coil designed to deliver precise handling and superior ride comfort for a wide range of Mitsubishi vehicles. Crafted with advanced metallurgy and precision engineering, this spring offers exceptional durability while maintaining the lightweight characteristics essential for modern automotive dynamics.

Key Technical Specifications

• Model Number: 4259249
• Type: Single coil spring (rear)
• Application: Mitsubishi Lancer Mk8, ASX MIVEC, and other models equipped with the 4A91/4A92/4B10/4N13 suspension systems.
• Material: High‑strength alloy steel with a proprietary heat‑treatment process to enhance fatigue resistance.
• Coil Diameter: Standard OEM dimensions compatible with the original rear axle assembly.
• Spring Rate: Optimized for balanced load distribution and responsive steering feel.

Design Features That Set It Apart

The spring incorporates a dual‑layer coil construction, which reduces the risk of metal fatigue while preserving stiffness. The outer layer provides structural integrity, whereas the inner layer absorbs dynamic loads, ensuring consistent performance over thousands of miles.

A unique surface finish treatment protects against corrosion and extends service life, even in harsh climates or when exposed to road salts. This finish also contributes to a quieter ride by minimizing metal‑to‑metal contact during suspension movement.

Installation Compatibility

This spring is engineered for seamless integration with the original rear axle assembly of Mitsubishi vehicles that use the 4A91, 4A92, 4B10, or 4N13 chassis. It fits both single and paired configurations, allowing mechanics to replace one or two springs as needed without modifying other suspension components.

Because it matches OEM specifications exactly, there is no need for additional hardware such as spacers or adapters. The spring can be installed using standard tools and follows the same procedure as the factory part.

Performance Benefits

• Improved Handling: The precise spring rate enhances cornering stability, giving drivers confidence on both city streets and winding roads.
• Enhanced Comfort: By absorbing road irregularities more effectively, the spring reduces vibration transmitted to the cabin.
• Long‑Term Reliability: The advanced alloy composition resists cracking and deformation under repeated loading cycles.
• Weight Efficiency: Despite its strength, the spring maintains a lightweight profile that supports overall vehicle performance.
