Bilstein 35-115106 Suspension Strut Assembly - Front Left

Bilstein B8 Front Left Strut for BMW E46

The Bilstein B8 Performance Plus strut assembly is a performance-focused replacement for OE dampers when paired with aftermarket lowering springs. This front left unit for select BMW 325Ci, 330Ci, 325i, 330i, 323Ci, 323i, 328Ci, and 328i applications uses Bilstein’s monotube internal design and application-specific valving to support sharper handling and a lower stance.

Part number 35-115106 is finished in Bilstein’s yellow paint and includes a blue bellows boot. It is built as a shortened strut for lowered suspension setups, making it a direct choice for drivers upgrading the front suspension on BMW 3 Series coupe and sedan models.

Product Details

Bilstein B8 Performance Plus dampers are engineered for vehicles running aftermarket lowering springs, and this 35-115106 front left strut follows that formula for select BMW E46 chassis models. The monotube design helps maintain controlled damping performance, while the shortened strut body supports proper suspension travel in lowered applications. For BMW 325Ci, 330Ci, 325i, and 330i owners, as well as 323Ci, 323i, 328Ci, and 328i drivers, this part provides a focused suspension upgrade with Bilstein build quality.

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

Installation Notes

Install this strut on the front left position only and verify that the vehicle is equipped with lowering springs or a lowered suspension setup. Confirm the stem upper mount and base cup lower mount configuration before installation, and match the shortened 45mm strut specification to the application. Professional installation and a post-installation alignment are recommended after suspension service.
