Steer straight and keep the front wheel located with the Delphi control arm TC3747, a direct-fit replacement for the 2015-2019 Ford Transit-150, Transit-250, Transit-350 and Transit-350 HD. Cataloged for the front right lower position, it anchors the lower suspension and provides the ball-joint pivot for that corner, allowing controlled wheel travel while helping hold your alignment settings.
Delphi carries its OE steering expertise into the aftermarket, testing parts from below -40°C to over 120°C and through 720 hours of salt spray, with dimensional and material analysis for close OE compatibility.
- Verified integrity: 100% crack detection and ultrasonic flaw detection confirm the material matches OE specifications.
- Robot-welded: automated welding for consistent construction and quality.
- Precision ball studs: machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Clunking over bumps, wandering steering or uneven tire wear can signal a worn control arm; diagnose the cause first, and if this arm is the culprit, TC3747 replaces it. This listing covers the right-side unit only.
