Keep your front suspension precisely located with the Delphi control arm and ball joint assembly TC2972 — a Delphi control arm engineered for the front left upper position on a broad range of Audi and Porsche vehicles. The arm helps support and locate the suspension while its integrated ball joint lets the steering and suspension pivot, and it drops in as a direct-fit replacement for the listed applications.
OE-level validation: Delphi tests to extremes — parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray, backed by extensive dimensional and material analysis for the best OE-to-aftermarket compatibility.
Flaw detection: Every control arm undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
Machined ball studs: Ball studs are machined to micron tolerances for durability and smooth joint operation.
Corrosion protection: Robot welding delivers consistent quality, and anti-corrosion protection is applied to each part for corrosion prevention and enhanced aesthetics.
