Product Details

This FCS front left strut assembly is specified for vehicles that use a conventional suspension setup in the listed applications. The dimensional specs help confirm the assembly’s travel range and overall fitment profile, which is important when replacing a worn strut on a Toyota Highlander or Lexus RX350. For Lexus RX330 and RX350 models, verify that the vehicle is not equipped with air suspension before ordering. This part number, 4331660L, is a focused replacement option for restoring front suspension function on the exact listed vehicles.

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

What This Part Helps Address

• Front-left suspension noise from a worn strut assembly
• Excessive bouncing or reduced damping control
• Uneven front ride height caused by a fatigued coil spring assembly
• Handling instability during braking, cornering, or lane changes
• Suspension wear on high-mileage Toyota Highlander and Lexus RX vehicles

Installation Notes and Tips

Confirm year, model, and front left position before installation. On Lexus RX330 and RX350 applications, verify the vehicle does not have air suspension, since this assembly is not listed for that configuration. Compare the original strut assembly dimensions and mounting layout to the replacement part number 4331660L before beginning service.

Quality Assurance

FCS suspension components are cataloged for specific vehicle applications and dimensional fitment. Use the listed vehicle coverage and suspension configuration notes to confirm correct selection for your Toyota Highlander, Lexus RX330, or Lexus RX350.
