Detailed Description

FCS 343358L is a suspension strut assembly for the front left side of Lexus IS sedans in the listed applications. The dimensional specs are important for maintaining correct suspension geometry and travel, especially when replacing a worn strut on a Lexus IS300, Lexus IS350, or Lexus IS250. FCS 343358L is identified for 2014-2018 Lexus IS fitments, with coverage varying by model and year.

FCS is the brand line shown for this part, and this strut assembly is cataloged under that product line for the specified Lexus applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Excessive front-end bounce over bumps
• Uneven ride height or suspension sag at the front left corner
• Noisy or worn strut performance during normal driving
• Reduced steering stability on Lexus IS300, IS350, or IS250 models
• Front suspension wear that affects ride control and handling response

Installation Notes and Tips

Verify the vehicle year, model, and front left position before installation. Compare the compressed length, extended length, and stroke length to the removed unit to confirm the correct replacement. After installation, inspect related suspension components and perform a wheel alignment if required by the repair procedure.
