Application Details

Fits 2001-2005 Lexus IS300, front right lower. Delphi TC6604 is built for the suspension geometry used in this application and is intended to restore proper control arm function on the Lexus IS300 front suspension. This part cross-references MOOG Chassis Products (e.g., RK642103) for the same application.

What This Part Helps Address

• Excessive front suspension play
• Clunking or knocking from the lower control arm area
• Uneven tire wear related to worn suspension bushings
• Steering pull caused by worn front right lower suspension components
• Loss of stable wheel control over bumps and braking

Installation Notes and Tips

Confirm the vehicle is a 2001-2005 Lexus IS300 and verify the front right lower position before installation. Because the ball joint is not included, inspect related suspension components during service and replace any worn mating parts as needed. After installation, a professional wheel alignment is recommended to help maintain correct handling and tire wear.

Quality Assurance

Delphi applies OE-focused engineering and dimensional analysis to support fit and compatibility with the original suspension layout. The part is also tested across extreme temperatures and salt-spray exposure to evaluate material performance in demanding conditions.
