Delphi TC3488 Suspension Control Arm - Rear Upper Rearward

OE-Style Rear Upper Rearward Control Arm

Delphi TC3488 is a suspension control arm built for the rear upper rearward position on select BMW applications. It uses stamped steel construction with rubber bushings and a black cataphoresis finish to support consistent fitment and corrosion resistance in everyday driving conditions.

Compatible with 2009-2017 BMW X3 and 2015-2018 BMW X4, this rear upper rearward control arm is a direct replacement option for restoring suspension geometry and ride control. Delphi TC3488 is engineered with OE-focused dimensional and material analysis to match the original part more closely.

Key Features

• Stamped steel construction for strength and OE-style fit
• Rubber bushings included for rear suspension mounting points
• Black cataphoresis finish for added surface protection
• Standard replacement grade for routine suspension service
• Non-adjustable design for direct replacement use
• Fits the rear upper rearward position

Detailed Description

Delphi TC3488 is a suspension control arm for BMW rear suspension service, specifically the rear upper rearward location. It is built from steel with a stamped construction and includes bushings already installed, helping simplify replacement of worn suspension components. The part number TC3488 is a practical match for drivers servicing BMW X3 and BMW X4 rear suspension wear, alignment concerns, or handling changes caused by aging control arm bushings.

Delphi applies OE-level testing and material analysis to its aftermarket steering and suspension portfolio. This control arm is evaluated for temperature extremes and salt-spray exposure, supporting durability in demanding road conditions. This part cross-references Beck/Arnley 102-7974 for the same application.

What It Helps Address

• Rear suspension looseness or clunking from worn bushings
• Uneven tire wear related to rear suspension geometry
• Excessive rear-end movement over bumps and road joints
• Alignment instability after suspension wear develops
• Replacement needs for a damaged rear upper rearward control arm

Installation Notes and Tips

Install TC3488 in the rear upper rearward position only. Mounting hardware is not included, so verify the condition of existing fasteners before beginning service. Because this control arm uses rubber bushings and a non-adjustable design, final alignment should be checked after installation on the BMW X3 or BMW X4.

Quality Assurance

Delphi uses OE-based dimensional and material analysis to support fit and function, and its suspension components are tested under extreme temperature and corrosion conditions. TC3488 is a standard replacement part built to meet the demands of everyday suspension service.
