Locate the front wheel and help support the suspension with the Mevotech Supreme control arm (CMS801148), a front left lower unit engineered as a direct-fit replacement for the 2004-2007 Subaru Impreza. This control arm and ball joint assembly integrates the arm and its ball joint into one piece, so a worn or loose ball joint is serviced together with the arm in a single install.
It replaces the front left lower control arm on the 2004-2007 Subaru Impreza — see the Buyer's Guide tab for engine-specific coverage. This listing is for the left side and is sold individually; order the matching right-side arm to service both sides of the axle for balanced handling.

This part cross-references / interchanges with the following part numbers:
What does this Mevotech Supreme assembly replace?
It replaces the front left lower control arm and its integrated ball joint on the 2004-2007 Subaru Impreza, combining both into a single bolt-in unit.
Is this the right part for a Subaru Impreza control arm replacement?
Yes — it's a direct-fit front left lower replacement for the 2004-2007 Subaru Impreza. Check the Buyer's Guide tab to confirm the engine and trim for your vehicle.
Is mounting hardware included?
Yes. The assembly comes with the part-specific castle nut and cotter pin needed to secure the ball joint to the vehicle.
What is it made of?
The control arm uses stamped steel construction with a protective surface treatment that resists rust build-up, and its ball joint rides on sintered bearings.
Do I need a separate control arm bushing for my Subaru Impreza?
No. This is a complete arm assembly, so its control arm bushings and ball joint come already installed — you don't source them separately.
