Product Description

The Bilstein 22-113313 is a B4 OE Replacement front strut assembly covering all 1997-2004 Porsche Boxster (986) variants - Base, Roadster, Roadster S, S, and S Special Edition - across all engine variants (2.5L, 2.7L, and 3.2L flat-six). As the direct cross-reference to multiple Porsche OEM part numbers including 986 343 041 20 and 986 343 041 37, this strut is precision-engineered to restore the 986's factory ride quality, steering response, and handling characteristics. The twin-tube gas pressure design ensures consistent damping output and fade resistance, delivering the sharp, connected feel the 986 Boxster is known for.

This is a direct bolt-on replacement that installs using the factory mounting hardware and reuses the OE spring - no spring replacement or special tools are required, though two assemblies are needed for a complete front installation. Designed for stock ride height applications, it is not recommended for use with lowering springs. The factory dust boot is reused during installation as no boot is included. Backed by Bilstein's limited lifetime warranty and manufactured to OE production standards, the 22-113313 is the benchmark front strut replacement for restoring the 986 Boxster's suspension to factory specification.
