OE Replacement Details

The Bilstein B3 OE Replacement line is focused on restoring original suspension function rather than changing vehicle behavior. This coil spring is engineered to match the original spring specifications used on the vehicle, helping return the front suspension to factory ride height and load support. For Mercedes-Benz ML350, ML550, ML320, and ML500 models, part number 36-166640 provides an OE-style replacement for standard suspension setups.

This part cross-references Lesjofors 4056870 for the same application.

What It Helps Address

  • Front-end sag from fatigued or broken original springs
  • Uneven ride height caused by spring wear
  • Loss of factory suspension geometry after spring deterioration
  • Reduced load support from weakened coil springs
  • Restoration needs after replacing worn OE suspension components

Installation Notes

Verify standard suspension fitment before ordering, since this spring is not listed for air or alternate suspension configurations. Confirm the vehicle year, model, and front position against the fitment data for Mercedes-Benz ML350, ML550, ML320, and ML500 applications. Professional spring installation and alignment checks are recommended after replacement.

Quality Assurance

Bilstein manufactures B3 OE Replacement springs to OE dimensions, spring rates, and design types to support factory-spec suspension restoration. The black powder coat finish adds a durable protective layer for everyday road use.
