Cusco Rear Trailing Arm for 1993-2007 Subaru Impreza WRX GC8/GD Chassis
This Cusco Rear Trailing Arm replaces the factory unit on Subaru Impreza WRX GC8 and GD chassis models from 1993 to 2007, fitting Base, L, RS, WRX, and STI trims. It minimizes deflection under load for sharper rear suspension response, confident cornering, and improved stability. High-tensile steel construction and spherical bearings ensure precise geometry and traction during aggressive driving.
Key Features
- Steel Pipe Construction: High-tensile steel tubing withstands track abuse and daily driving stresses far beyond OEM limits
- Spherical Bearing Mount: Pillow ball at forward position allows precise articulation and eliminates bushing slop for direct steering feedback
- OEM Direct Fitment: Bolts in place of stock trailing arm with no modifications required on GC8 or GD chassis
- Reduced Deflection: Maintains rear geometry during hard cornering to improve traction and reduce understeer
- Powder Coated Finish: Durable black coating resists corrosion and simplifies cleaning after track sessions
Product Notes
- Inspect bushings and bearings during annual suspension service for longest life
- Use Cusco recommended grease on spherical bearings to prevent premature wear
- Package arrives fully assembled ready for installation
Installation Notes
- Professional installation recommended.
- Torque all bolts to Subaru factory specifications after alignment
- Requires rear wheel alignment post-install to restore camber and toe settings

Suspension Arms & Components
Suspension arms and components include the control arms, camber adjustment arms, traction bars, toe arms, and tie rod assemblies that define suspension geometry and connect the wheel hubs to the vehicle chassis. Quality suspension arm upgrades correct geometry on modified vehicles and replace worn factory components to restore precise handling. Popular Suspension Arm Upgrades Popular suspension arm upgrades include adjustable rear camber arm kits for correcting camber on lowered vehicles, rear traction arm replacement kits, tubular front lower control arms for improved geometry and clearance, adjustable toe arm kits, upgraded tie rod ends with improved ball joint construction, and full rear suspension arm upgrade packages for popular sport and performance platforms.
