Delphi TC4720 Lateral Arm - Rear Upper Rearward

Delphi TC4720 Rear Upper Rearward Lateral Arm

The Delphi TC4720 is a stamped steel lateral arm built for the rear upper rearward suspension position on select Mercedes-Benz models. It uses rubber bushings and a painted black finish to support OE-style suspension geometry and consistent rear suspension movement.

• Stamped steel construction
• Black painted finish with matte appearance
• Rubber bushings included
• Bushing-to-fork design
• Standard replacement grade
• Non-adjustable, non-greaseable design
• Rear Upper Rearward position

OE-Style Suspension Replacement

Delphi applies OE-focused dimensional and material analysis to its aftermarket steering and suspension portfolio, and the TC4720 follows that approach for fit and function. It is engineered as a direct replacement lateral arm for the rear upper rearward location on 2019 Mercedes-Benz A250, 2019-2022 Mercedes-Benz A220, 2020-2023 Mercedes-Benz CLA250, 2020-2023 Mercedes-Benz GLB250, and 2021-2023 Mercedes-Benz GLA250. This part number, TC4720, is also referenced for the same application under cross-reference part numbers 247-350-17-00 and A 247 350 17 00.

What This Part Helps Address

• Excessive rear suspension play from worn arm bushings
• Noisy suspension movement over bumps or uneven roads
• Imprecise rear wheel location affecting alignment stability
• Corrosion-related wear on the original lateral arm
• Handling changes caused by fatigued suspension components

Installation Notes

Verify the rear upper rearward position before installation and compare the original arm length, bushing style, and mounting hole diameter to the replacement part. The TC4720 is not adjustable and does not include mounting hardware, so reuse or source hardware as required by the vehicle service procedure. Because this arm uses rubber bushings and a stamped steel body, proper torque and alignment checks after installation are important for Mercedes-Benz CLA250, GLA250, GLB250, A220, and A250 applications.

Quality Assurance

Delphi subjects its OE-inspired suspension components to extreme temperature testing below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure, to evaluate durability in harsh conditions. The TC4720 is built to standard replacement specifications for consistent service on the listed Mercedes-Benz fitments.
