Key Features

• Steel construction for suspension strength and durability
• Black cataphoresis finish for added corrosion resistance
• Natural rubber bushings included
• Straight, non-adjustable design
• Standard replacement part for the rear right upper position
• Delphi TC5879 part number for easy identification

Detailed Description

Delphi TC5879 is a rear right upper suspension control arm made for OE-style replacement on the Lexus NX300, Lexus NX300h, Lexus NX200t, and Toyota RAV4. It uses a steel body, rubber bearing type, and natural rubber bushings to match the suspension layout required for the listed applications. The non-adjustable design and 296.5 mm mounting-hole distance support proper fitment where the original suspension arm uses the same configuration. Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, and its OE-based dimensional and material analysis helps maintain close compatibility with the original part.

This part cross-references Dorman OE Solutions 524-006 and MOOG Chassis Products RK641739 for the same application.

• Uneven tire wear caused by worn rear suspension geometry
• Handling instability from deteriorated bushings
• Failed inspection due to damaged or corroded suspension components

Installation Notes and Tips

Verify the rear right upper position and confirm the vehicle uses the non-adjustable configuration before installation. Inspect adjacent suspension hardware, bushings, and mounting points for wear or corrosion, and replace any damaged components as needed. Because mounting hardware is not listed as included, reuse or source the correct hardware separately if required by the vehicle.

Quality Assurance

Delphi applies OE-focused engineering and validation to its aftermarket steering and suspension portfolio. TC5879 is tested for temperature extremes and salt-spray exposure to help support long-term performance in demanding road conditions.
