Product Details

The Bilstein B3 OE Replacement line is focused on restoring original suspension function rather than changing vehicle behavior. This rear coil spring is engineered to match the factory spring specifications used on select Mercedes-Benz C-Class models, helping return the vehicle to its original stance and load-carrying characteristics. If you are replacing a fatigued rear spring on a Mercedes-Benz C230, C280, C350, C240, C320, or C220, 36-226160 provides an OE-style solution built around the original application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes

Verify rear suspension configuration and model-year application before ordering, especially on Mercedes-Benz C230, C280, and related C-Class variants with heavy duty or trim-specific notes. Replace springs in matched pairs when service history and condition call for it, and inspect related suspension components during installation to confirm proper ride height and alignment after repair.

Quality Assurance

Bilstein B3 OE Replacement springs are manufactured to OE dimensions, spring rates, and design types to support factory-spec suspension restoration. The black powder coat finish adds a durable protective layer to the spring surface.
