Cusco’s rear trailing arm for WRX GC/GD applications replaces or upgrades the rear suspension arm assembly used on those Subaru platforms. Intended as a direct-replacement suspension link, it restores proper trailing arm fitment and alignment where the original component is worn. Use it when servicing the rear suspension or rebuilding rear linkage on compatible WRX models.
