Delphi TC4608 Suspension Control Arm and Ball Joint Assembly - Front Right Lower Forward

OE-Style Suspension Control Arm

Delphi TC4608 is a suspension control arm and ball joint assembly built for the front right lower forward position. It is engineered for BMW applications that require precise suspension geometry and consistent steering response.

With OE-focused dimensional and material analysis, this part is built to match the original fit and function expected in the chassis. Delphi TC4608 is a direct-fit replacement for select BMW models, including 640i xDrive Gran Coupe, 650i xDrive Gran Coupe, and 528i xDrive applications.

Key Features

• Front right lower forward suspension control arm and ball joint assembly
• OE-based fitment analysis for accurate compatibility
• Tested for extreme temperature exposure from below -40 C to over 120 C
• Exposed to 720 hours of salt spray testing for corrosion resistance validation
• Built for BMW suspension systems that rely on precise alignment control

Detailed Description

Delphi TC4608 is part of Delphi’s OE-focused steering and suspension portfolio. The design reflects extensive dimensional and material analysis to help maintain the original suspension relationship between the control arm, ball joint, and surrounding components. For BMW 640i xDrive Gran Coupe, 650i xDrive Gran Coupe, 535i xDrive, and related xDrive models, this assembly supports accurate front suspension operation and consistent road feel.

This part cross-references Dorman - OE Solutions 526-798 and MOOG Chassis Products RK623381 for the same application. The TC4608 part number is also useful when verifying the correct front right lower forward control arm assembly during service or replacement.

What It Is Used For

• Restoring worn suspension geometry
• Replacing a loose or noisy ball joint assembly
• Correcting steering wander or uneven handling response
• Addressing suspension play that can affect alignment stability
• Replacing a damaged control arm in BMW xDrive suspension systems
