Tighten up steering response and restore proper front suspension geometry with the Mevotech Supreme control arm and ball joint assembly (CMK90383). It installs as a direct-fit front right lower unit for the 2003-2005 Kia Rio, combining the control arm, integrated ball joint, and mounting hardware in one ready-to-bolt package.
Mevotech Supreme parts are engineered in-house with application-specific upgrades for added durability, and this assembly is built for everything from daily-driven passenger cars to high-usage fleet and working-truck duty.
- Forged steel construction: built to OE-level specifications for strength under load.
- All essential mounting hardware included: the Labor Saver design speeds up installation.
- Corrosion-resistant surface treatment: helps prevent rust build-up for longer part life.
- Rigorously tested: extensive in-house and third-party durability testing.
The lower control arm locates the wheel while its integrated ball joint lets the suspension and steering pivot and travel, keeping the wheel positioned. Clunking over bumps, loose or wandering steering, and uneven front tire wear are signs the original control arm or ball joint may need replacing. As a Mevotech Supreme lower control arm, this Mevotech Supreme suspension control arm bolts in as a complete front-corner unit.
