Detailed Description

Lesjofors 4008501 is a front coil spring built for BMW suspension service where original ride height, load support, and handling balance matter. It is manufactured from high-strength steel and processed with heat treatment, shot peening, zinc phosphate coating, and epoxy powder coating to help maintain durability in demanding road conditions. This spring is a direct replacement for 2012 BMW 528i and 2012 BMW 528i xDrive applications equipped with M-technology, and it cross-references BMW OE numbers 31336795427 and 31336795428 for the same application.

What It Helps Fix

• Sagging front ride height
• Uneven stance after spring fatigue
• Noisy or weakened suspension support
• Reduced steering response from worn front springs
• Ride quality changes caused by a damaged coil spring

Installation Notes and Tips

Install 4008501 on the front axle only and verify M-technology suspension configuration before ordering. Replace springs in axle pairs when wear is present on both sides to help maintain balanced ride height and handling. A professional spring compressor and proper suspension service procedures are recommended during installation.
