• Steel and aluminum construction with casting/forged design
• Includes bushings with natural rubber (NR) bushing material
• Gray bushing color and silver arm finish
• Standard replacement grade for OE-style service
• Not pre-greased and no ball joint included
• Compatible with BMW 740i, 740Li, 750i, 750i xDrive, 750Li, 750Li xDrive, and 760Li applications listed below

Detailed Description

Delphi TC3377 is built for BMW rear suspension service where precise arm location and bushing performance matter. Delphi applies OE-level dimensional and material analysis to help ensure proper compatibility with the original suspension layout, while the arm is tested across extreme temperature and corrosion conditions to support long-term durability. This part cross-references Dorman - OE Solutions 524-662 for the same application.

For fitment, this control arm fits 2011-2012 BMW 740i, rear right upper forward; 2011-2012 BMW 740Li, rear right upper forward; 2009-2012 BMW 750i, rear right upper forward; 2010-2012 BMW 750i xDrive, rear right upper forward; 2009-2012 BMW 750Li, rear right upper forward; 2011-2012 BMW 750Li xDrive, rear right upper forward, 355mm Length; 2010-2011 BMW 760Li, rear right upper forward; 2012 BMW 760Li, rear right upper forward, 355mm Length; and 2010 BMW 750Li xDrive, rear right upper forward.

What It Helps Address

• Rear suspension looseness or imprecise handling
• Clunking or knocking from worn rear control arm bushings
• Uneven rear tire wear caused by suspension geometry issues
• Excess movement at the rear right upper forward suspension point
• Restoration of OE-style rear suspension alignment on BMW 7 Series models

Installation Notes and Tips

Verify the rear right upper forward position and compare the original arm length, mounting points, and bushing layout before installation. Mounting hardware is not included, and the arm is not adjustable. Because this part is not pre-greased and does not include a ball joint, inspect adjacent suspension components and replace any worn hardware or related bushings as needed during service.

Quality Assurance

Delphi uses OE safety technology and applies OE-focused testing to its aftermarket steering and suspension portfolio. TC3377 is evaluated for temperature resistance and salt-spray exposure, along with dimensional and material analysis to support fit and durability in BMW rear suspension applications.
