The Story
Rear Left Trailing Arm for Subaru Fitment
Delphi TC7558 is a rear left suspension trailing arm built for specific Subaru applications, including the Impreza, WRX, WRX STI, and Forester. It uses a steel arm with a black finish and a rubber bushing already included for a direct replacement on the rear left side.
Key Features
- Steel construction for suspension strength and durability
- Black finish with black bushing color
- Rubber bushing included
- Non-adjustable design
- Rear left position
- Length: 16.53 in. (420.3 mm)
- Mounting hole diameters: 0.51 in., 0.79 in., 13.0 mm, and 20.2 mm
Detailed Description
Delphi TC7558 suspension trailing arm is engineered for rear left installation on 2008-2014 Subaru Impreza, 2013-2014 Subaru WRX, 2013-2014 Subaru WRX STI, and 2009-2013 Subaru Forester. Delphi applies OE-level dimensional and material analysis to support fitment consistency between the original part and the aftermarket replacement. The arm is made from steel, measures 16.53 inches in length, and includes a black rubber bushing for the end connection.
This part cross-references MOOG Chassis Products RK643598 for the same application.
What This Part Helps Address
- Rear suspension looseness or instability on the left side
- Excessive play from a worn trailing arm bushing
- Clunking or knocking from rear suspension movement
- Uneven rear wheel tracking caused by a damaged arm
- Corrosion or structural wear in the original trailing arm
Installation Notes
Fits 2008-2014 Subaru Impreza, rear left. Fits 2013-2014 Subaru WRX, rear left. Fits 2013-2014 Subaru WRX STI, rear left. Fits 2009-2013 Subaru Forester, rear left. Mounting hardware is not included, so reuse or source the correct fasteners as needed. Verify mounting hole sizes and suspension geometry before installation, and confirm the rear left position matches the vehicle application.
Quality Assurance
Delphi subjects its OE-based steering and suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing. That testing approach supports material durability and dimensional consistency for Subaru Impreza, WRX, WRX STI, and Forester applications.
