Delphi TC3088 Suspension Control Arm - Rear Right Upper or Rear Right Upper Rearward

OE-Style Rear Right Upper Control Arm

Delphi TC3088 is a suspension control arm built for the rear right upper position on select Audi applications. It uses pressed steel construction with a stamped design, black finish, and natural rubber bushings to support stable suspension movement and consistent alignment geometry.

Compatible with Audi A4, Audi A4 Quattro, Audi S4, and Audi RS4 applications listed below, this Delphi control arm is a standard replacement part engineered with OE-focused dimensional and material analysis.

Key Features

• Pressed steel construction with stamped arm design
• Black cataphoresis finish for added surface protection
• Natural rubber bushings included
• Standard replacement grade for rear suspension service
• Designed for the rear right upper and rear right upper rearward positions
• Delphi TC3088 part number for direct catalog matching

Detailed Description

Delphi TC3088 is a rear suspension control arm engineered for OE-style fit and function on select Audi models. The arm measures 355.0 in length with a 145.0 width and uses rubber bearing material with black bushings to help maintain suspension articulation and ride control. It does not include a ball joint, is not pre-greased, and does not include mounting hardware.

Delphi applies OE-level dimensional and material analysis to help ensure proper compatibility with the original suspension layout. The part is tested for extreme temperature exposure and salt spray resistance as part of Delphi’s aftermarket steering and suspension validation process. This makes the TC3088 a practical replacement for worn rear suspension components on Audi A4, Audi A4 Quattro, Audi S4, and Audi RS4 vehicles.

This part cross-references MOOG Chassis Products RK642640 for the same application.

What It Helps Address

• Rear suspension looseness or play
• Clunking or knocking from the rear control arm area
• Uneven tire wear caused by worn suspension geometry
• Alignment instability after bushing wear
• Handling drift or reduced rear-end control

Installation Notes and Tips

Install Delphi TC3088 in the rear right upper position, or rear right upper rearward position where specified by the vehicle application. Because mounting hardware is not included, reuse or replace fasteners as required by the vehicle service procedure. After installation, perform a professional wheel alignment to verify suspension geometry.

Fitment includes 2002-2009 Audi A4, rear right upper; 2002-2009 Audi A4 Quattro, rear right upper; 2004-2009 Audi S4, rear right upper; 2007-2008 Audi A4, rear right upper rearward; 2007-2008 Audi RS4, rear right upper; and 2002 Audi S4, rear right upper with VIN restrictions noted in the catalog.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for this suspension control arm, including dimensional and material analysis plus environmental testing for temperature extremes and salt exposure. The result is a replacement part built to align with the original suspension design requirements for the listed Audi applications.
