Detailed Description
Delphi TC6446 is a rear stabilizer bar link for the Lexus LS400 that helps connect the sway bar to the suspension assembly and maintain rear-end stability during cornering and road input changes. Delphi applies OE-focused dimensional and material analysis to support proper fitment, and this part is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Rear suspension clunking from a worn stabilizer link
- Excessive sway-bar play affecting handling feel
- Loose or inconsistent rear suspension response
- Noise caused by deteriorated link joints or boots
- Fitment issues when replacing a worn Lexus LS400 rear link
Installation Notes and Tips
Verify rear-position fitment before installation on 1995-2000 Lexus LS400 applications. Confirm bolt thread size M12 x 1.25 and compare the original link length and mounting-hole spacing to the removed part. Inspect adjacent sway bar bushings, control arm hardware, and mounting points for wear before completing the repair.
Quality Assurance
Delphi uses OE-based engineering practices for aftermarket steering and suspension components, including dimensional and material checks to support proper part matching. TC6446 is evaluated for temperature resistance and corrosion exposure as part of Delphi’s durability testing process.
