Rear Upper Control Arm for 2015-2018 BMW X4 & More - Delphi TC3488

Help keep the wheel precisely located and the ride quiet and controlled with the Delphi control arm TC3488, a rear upper rearward suspension control arm that installs as a direct-fit replacement for the 2009-2012 BMW X3. The control arm locates the wheel and links the suspension to the chassis; when its bushings or integrated ball stud wear, you may notice clunking over inputs, loose or wandering steering, or uneven tire wear — signs this part may need replacing.

• Tested to OE extremes: validated below -40°C and above 120°C and exposed to 720 hours of salt spray, with dimensional and material analysis for close compatibility to the original.
• 100% inspected: every arm gets crack detection and ultrasonic flaw detection so materials match OE specifications.
• Robot-welded: consistent, repeatable weld quality across every part.
• Micron-machined ball studs: machined to micron tolerances for smooth joint operation and durability.
• Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

Delphi's OE safety technology is fitted to millions of vehicles worldwide, and that OE expertise carries into this aftermarket steering and suspension portfolio.
