Detailed Description
Delphi TC7188 is engineered as a suspension control arm and ball joint assembly for the rear upper forward location on select Lexus models. It is a direct replacement for 1998-2005 Lexus GS300, 1998-2000 Lexus GS400, 2001-2005 Lexus GS430, and 2002-2010 Lexus SC430. This part cross-references Beck/Arnley 102-7884 for the same application.
Delphi uses OE-based material and dimensional analysis to support fitment consistency between the original part and the aftermarket replacement. The assembly is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding road conditions. Delphi TC7188 is a practical choice when replacing a worn rear upper forward control arm on Lexus GS300, GS400, GS430, or SC430 suspension systems.
Common Problems This Part Can Help Solve
