Delphi TC6744 Suspension Control Arm - Front Left Lower

OE-Style Front Left Lower Control Arm

Delphi TC6744 is a front left lower suspension control arm built for select Lexus applications that use a steel arm. It combines stamped steel construction, pre-greased service readiness, and rubber bushings to support stable suspension movement and consistent alignment geometry.

Fits 2006-2015 Lexus GS300, GS350, GS430, GS450h, GS460, IS250, and IS350, front left lower, with application-specific notes for steel arm and non-Sport Package models where listed.

Key Features

• Stamped steel construction with a black finish
• Pre-greased for service-ready installation
• Rubber bushings included
• Press-in ball joint mounting type with grooved stud design
• Standard replacement grade for OE-style suspension service
• Front left lower position
• Length: 425.0

Detailed Description

Delphi TC6744 suspension control arm is engineered for front left lower suspension service on select Lexus GS and IS models. Delphi applies OE-focused dimensional and material analysis to help ensure proper part-to-vehicle match, and each unit is tested across extreme temperature and corrosion conditions to verify durability in demanding environments. This part cross-references MOOG Chassis Products RK642162 for the same application.

For Lexus IS250 and IS350 fitments, this control arm applies to 2008 models from 08/2008 and 2009-2013 vehicles without the Sport Package, plus 2014-2015 vehicles with a steel arm. For Lexus GS300, GS350, GS430, GS450h, and GS460 applications, it serves the front left lower position on the listed steel-arm configurations.

What This Part Helps Address

• Excessive front suspension play from a worn control arm
• Clunking or knocking from deteriorated bushings or ball joint wear
• Uneven tire wear caused by suspension geometry issues
• Steering pull or wandering linked to front lower arm wear
• Alignment instability after suspension component fatigue

Installation Notes and Tips

Verify the vehicle’s steel-arm configuration, model year, and package notes before ordering. This front left lower control arm uses a press-in ball joint mounting type and does not include mounting hardware. Because it is not adjustable, final alignment should be checked after installation. Confirm the existing arm length and mounting style against the original part before service.

Quality Assurance

Delphi builds this suspension control arm using OE-based engineering practices and durability testing that includes extreme temperature exposure and salt-spray corrosion evaluation. The result is a standard replacement part intended to match the fit and function expected for Lexus GS and IS front suspension service. Part number TC6744 is also listed under common aftermarket cross-reference applications.
