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 dimensions and rate, helping preserve the intended stance, load support, and front-end response on Mercedes-Benz S-Class and related chassis applications. If you are replacing a fatigued spring on a Mercedes-Benz S420 or Mercedes-Benz S500, 36-233120 provides an OE-style solution for the front suspension.

This part cross-references Lesjofors 4056838 for the same application.

What It Helps Address

  • Sagging front ride height
  • Uneven stance from a worn spring
  • Loss of original suspension geometry
  • Factory ride quality changes caused by spring fatigue
  • Front suspension service on Mercedes-Benz S-Class models
