Product Details
The Bilstein B3 OE Replacement line is built for drivers who want to return the suspension to original specifications rather than change the vehicle’s ride characteristics. This coil spring is engineered to match the original spring geometry and rate, helping maintain proper stance, load support, and suspension function on the BMW 525i and BMW 528i. The 36-266722 spring is listed for front installation on 1999-2000 BMW 528i and 2001-2003 BMW 525i models with standard suspension only. This part cross-references Lesjofors 4008428 for the same application.
What This Spring Helps Address
- Sagging front ride height on BMW 525i and BMW 528i models
- Uneven stance caused by worn original coil springs
- Loss of factory suspension response from fatigued springs
- Restoration of OE ride characteristics after spring replacement
- Front-end suspension service on standard suspension vehicles
Installation Notes and Tips
Verify standard suspension before ordering, since this spring is not listed for other suspension configurations. Replace springs in line with the vehicle’s service procedure and inspect related suspension components such as strut mounts, isolators, and control arm bushings during service. Confirm the part number 36-266722 against the vehicle’s year, model, and front position before installation.
Quality Assurance
Bilstein manufactures B3 OE Replacement springs to meet original equipment dimensions, spring rates, and design requirements, supporting factory-spec suspension restoration for the BMW 525i and BMW 528i.
