Detailed Description

Lesjofors 4008428 is engineered as a replacement coil spring for BMW front suspension service. It is compatible with 1997-2000 BMW 528i front, 2001-2003 BMW 525i front, and 2001-2003 BMW 530i front, excluding M-technology models. This part cross-references BMW 31331093069 and 31331096184 for the same application. Lesjofors has a long spring-manufacturing history and supplies replacement springs built to meet OE-level requirements for fit and function.

Common Issues This Part Helps Address

• Sagging front ride height
• Uneven front suspension stance
• Broken or fatigued coil spring replacement
• Restoring factory-like spring support after wear
• Front-end suspension noise caused by a damaged spring

Installation Notes and Tips

Install on the front suspension only and verify exclusion for M-technology models before ordering. Because coil springs are under high tension, use proper spring-compression tools and follow BMW service procedures during removal and installation. Inspect related suspension components such as strut mounts, isolators, and bushings while the assembly is apart.

Quality Assurance

Lesjofors coil springs are manufactured with high-strength steel, heat treatment, shot peening, zinc phosphate coating, epoxy powder coating, and pre-setting, then tested for consistency. The brand’s spring-making background dates back to 1852, supporting its focus on OE-style replacement suspension components.
