Detailed Description

Delphi TC3781 is a suspension control arm designed to restore front-end suspension location and alignment on supported Kia models. Delphi applies OE-focused dimensional and material analysis to help ensure proper fit between the replacement part and the original suspension layout. The arm uses tubular steel construction with a black finish and includes bushings, while omitting a pre-greased design and grease fitting.

This part cross-references MOOG Chassis Products RK641574 for the same application. For shoppers comparing Kia Optima front left lower control arm options or looking for a Kia Rondo front suspension control arm, TC3781 provides a standard replacement solution built to match the OE-style mounting points and position requirements.

What It Helps Address

• Excessive front suspension play from worn control arm bushings
• Clunking or knocking from the front left lower suspension area
• Uneven tire wear caused by worn suspension geometry
• Steering pull or unstable road feel linked to lower control arm wear
• Alignment issues after suspension component deterioration

Installation Notes and Tips

Install in the front left lower position only. Verify vehicle year, model, and suspension configuration before ordering, especially for 2007 Kia Rondo applications with the 01/06/2007 note. Because mounting hardware is not included and the ball joint is not included, inspect related components before installation and replace worn hardware or joints as needed. A professional alignment is recommended after installation.

Quality Assurance

Delphi subjects its OE-based steering and suspension components to extreme temperature testing and extended salt-spray exposure to evaluate durability and corrosion resistance. The brand also uses dimensional and material analysis to support OE-style compatibility for aftermarket replacement.
