Delphi TC6170 Suspension Control Arm - Rear Upper

Rear Upper Suspension Control Arm

Delphi TC6170 is a rear upper suspension control arm built for OE-style replacement on select Acura and Honda applications. It uses stamped steel construction with a black cataphoresis finish and includes bushings for a direct service replacement on the rear upper position.

Key Features

• Stamped steel construction for strength and consistent fit
• Black cataphoresis finish for added corrosion resistance
• Bushings included; ball joint not included
• Non-adjustable, straight design
• Standard replacement grade for rear upper suspension service
• Delphi part number TC6170

Detailed Description

Delphi TC6170 is engineered as a rear upper suspension control arm for 2001-2006 Acura RSX, 2001-2005 Acura EL, and 2001-2005 Honda Civic rear upper applications. The steel stamped construction and OE-focused dimensional analysis help maintain proper suspension geometry and fitment where the original arm has worn, bent, or corroded. Delphi validates parts through extreme temperature exposure and salt-spray testing to support durability in demanding road conditions. If you are replacing a rear upper control arm on a Honda Civic or Acura RSX, Delphi TC6170 provides a direct replacement path with the correct mounting dimensions and bushing configuration.

This part cross-references Dorman - OE Solutions 522-642 for the same application.

What It Helps Fix

• Rear suspension noise from worn control arm bushings
• Excessive rear wheel movement caused by a bent or fatigued arm
• Uneven tire wear related to rear suspension geometry issues
• Clunking or looseness from deteriorated rear upper arm components
• Corrosion-related replacement needs on older Acura and Honda rear suspension systems

Installation Notes and Tips

Verify rear upper position fitment before installation. This arm is non-adjustable and does not include mounting hardware or a ball joint. Inspect adjacent bushings, fasteners, and alignment settings during service, and confirm the vehicle matches the listed Acura RSX, Acura EL, or Honda Civic rear upper application before replacement.

Quality Assurance

Delphi applies OE-based engineering, dimensional checks, and material analysis to support compatibility with the original suspension layout. The part is tested for temperature extremes and extended salt-spray exposure to help confirm durability in real-world use.
