Product Details

Bilstein B3 OE Replacement springs are engineered as factory-style replacements for worn or sagging original springs. By matching OE dimensions and spring rate, this spring helps return the Mercedes-Benz C300, C250, or C350 front suspension to the intended ride height and handling balance. The B3 OE Replacement line focuses on preserving original suspension behavior rather than changing it, making it a practical choice for maintenance and repair. This part number, 37-172350, is listed for sport suspension only on the confirmed applications.

This part cross-references Bosch 17231 for the same application.

What It Helps Address

  • Front-end sag from a fatigued coil spring
  • Uneven ride height on the Mercedes-Benz C300, C250, or C350
  • Loss of factory suspension response after spring wear
  • Noise or instability caused by a weakened front spring
  • Restoration of OE suspension geometry after spring replacement

Installation Notes

Verify the vehicle is equipped with sport suspension before ordering. Confirm the part number 37-172350 against the original spring and inspect related suspension components during service. Because coil springs are load-bearing components, proper spring compression tools and professional installation practices are required.

Quality Assurance

Bilstein manufactures the B3 OE Replacement line to OE dimensions, spring rates, and design types so the replacement matches factory specifications for the listed Mercedes-Benz applications.
