Keep your BMW's rear wheel precisely located with the Delphi control arm TC8394, a rear right upper forward suspension arm that installs as a direct-fit replacement for the 2004-2005 BMW 645CI, 2006-2010 BMW 650I, 2006-2008 BMW 750I, 2006-2008 BMW 750LI, 2006 BMW 760I, 2006-2008 BMW 760LI, and 2007-2008 BMW ALPINA B7. This arm connects the rear knuckle to the chassis, locating the wheel and helping maintain rear alignment geometry as the suspension moves.
- Robot-welded construction: welded by robot for consistent build and performance.
- OE-verified integrity: every arm goes through 100% crack detection and ultrasonic flaw detection so its material matches OE specifications.
- Precision ball studs: the ball studs are machined to micron tolerances for durable, smooth joint operation.
- Anti-corrosion protection: a corrosion-resistant treatment is applied to each part.
Delphi validates its steering and suspension parts hard: the parts withstand temperatures below -40°C and above 120°C and endure 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility. If a worn control arm or its ball joint is behind clunking over bumps, wandering steering, or uneven rear tire wear, replacing this arm addresses that worn component. Diagnose the cause before replacing.
