Delphi TC3789 Rear Lower Lateral Arm

Delphi TC3789 is a rear lower lateral arm built as a standard replacement for select BMW and Mini applications. It uses stamped steel construction with a painted black finish, rubber bushings, and a straight shape to match the original suspension layout.

Fits 2014-2024 BMW and Mini rear lower suspension applications, including BMW 228i Gran Coupe, BMW 228i xDrive Gran Coupe, BMW X1, BMW X2, Mini Cooper, Mini Cooper Clubman, and Mini Cooper Countryman.

  • Part number: TC3789
  • Material: steel with stamped construction
  • Black painted finish for corrosion resistance
  • Rubber bushings included; bushing color is black
  • End 1 and End 2 use bushing-style mounting
  • Rear lower position
  • Standard replacement grade, non-adjustable

OE-Style Suspension Replacement

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, using dimensional and material analysis to support proper part matching. TC3789 is built for rear lower suspension service on BMW 228i Gran Coupe, BMW X1, BMW X2, and Mini Cooper platform vehicles where a straight lateral arm with bushings is required. This part cross-references Mevotech Original Grade GS101453 and Mevotech Supreme CMS101453 for the same application.

What It Helps Address

  • Rear suspension looseness or instability
  • Clunking or knocking from worn bushings
  • Uneven tire wear related to rear alignment movement
  • Excess play in the rear lower control path
  • Restoration of factory-style suspension geometry

Installation Notes

Verify rear lower fitment by year, make, and model before installation. Mounting hardware is not included, so reuse or replace hardware as needed during service. After installation, a professional wheel alignment is recommended to confirm suspension geometry and tire wear settings.

Quality Assurance

Delphi tests suspension components for temperature extremes below -40 degrees C and above 120 degrees C, and exposes parts to 720 hours of salt spray to evaluate durability. TC3789 is backed by Delphi’s OE-focused manufacturing and validation process for aftermarket suspension replacement.
