Keep your front suspension precisely located and your steering smooth with the Delphi control arm and ball joint assembly, part number TC9137. This DELPHI control arm drops in as a direct-fit replacement for the 2022-2025 BMW I4 (All), mounting in the front left rearward position, where it locates the wheel, absorbs suspension travel, and — through its integrated ball joint — lets the wheel steer and articulate.

  • OE-grade testing: Built on Delphi's OE steering expertise and validated to extremes — performance from below -40°C to over 120°C plus 720 hours of salt-spray exposure, with dimensional and material analysis for close OE compatibility.
  • 100% inspected: Every arm undergoes crack detection and ultrasonic flaw detection so the material matches OE specifications.
  • Precision ball studs: Ball studs machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded & corrosion-protected: Robotic welding delivers consistent quality, and anti-corrosion protection helps guard against corrosion.

Made in Turkey.
