Keep your BMW's rear suspension precisely located with the Delphi control arm, MPN TC1945 — a direct-fit rear upper center arm that positions the wheel and supports the suspension load through its integrated ball stud. It fits many vehicles, among them the 2008-2012 BMW 128I, 2008-2012 BMW 135I and 2007-2012 BMW 328I. See the Buyer's Guide tab for the full list and engine-level fitment.
- OE-based engineering: built on Delphi's OE expertise, with dimensional and material analysis for close OE compatibility.
- Precision ball studs: machined to micron tolerances for durable, smooth joint operation.
- Quality-verified construction: robot welding for consistent build, plus 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Anti-corrosion protection: applied to each part; tested from below -40°C to over 120°C and through 720 hours of salt spray.
If a worn rear upper suspension control arm or its ball joint is behind clunking, wander, or uneven tire wear, this replaces it.
