Detailed Product Overview

Delphi applies OE-level dimensional and material analysis to its aftermarket steering and suspension portfolio, helping support proper fit and function. TC3879 is engineered for the front right position on 2014-2020 Mini Cooper and 2021-2024 Mini Cooper Front Right Lower applications. The steel stamped design, coated finish, and rubber bushing construction are selected for everyday suspension service where consistent geometry and replacement accuracy matter. Delphi TC3879 is a practical choice when replacing a worn front right control arm on a Mini Cooper.

This part cross-references OE numbers 31 12 6 850 398 and 31126879842 for the same application.

What This Part Helps Address

• Excessive front-end looseness or wandering
• Clunking or knocking from the front right suspension
• Uneven tire wear related to worn suspension geometry
• Steering response changes caused by worn bushings or ball joint wear
• Inspection failures tied to damaged control arm components

Installation Notes and Tips

Install TC3879 on the front right side only for the listed Mini Cooper applications. Verify suspension orientation before installation, and inspect adjacent components such as tie rods, struts, and alignment settings during service. Because the ball joint and bushings are included, this control arm supports a complete front right replacement on the specified vehicles.

Quality Assurance

Delphi subjects its steering and suspension parts to extreme temperature and corrosion testing, including sub-zero and high-heat exposure and extended salt-spray evaluation. That testing, along with OE-based dimensional and material analysis, supports consistent replacement quality for Mini Cooper suspension service.
