Detailed Description

Delphi TC5521 is a suspension stabilizer bar link for the front left position, designed for Lexus IS250, IS300, IS350, RC300, RC350, GS300, and GS350 applications. It measures 123.0 mm in length and uses male M12 x 1.25 threaded ends for direct-fit installation on the listed vehicles. Delphi applies OE-focused dimensional and material analysis to help maintain proper compatibility between the replacement part and the original suspension layout. The part number TC5521 is a practical choice when replacing a worn front sway bar link on a Lexus IS350 front left or a Lexus GS350 front left, as well as other listed Lexus fitments.

What It Helps Address

• Front-end clunking or rattling from a worn stabilizer link

• Restoring proper stabilizer bar connection on Lexus IS250, IS300, IS350, RC300, RC350, GS300, and GS350 models

Installation Notes and Tips

Verify the front left position and confirm the M12 x 1.25 thread specification before installation.
