Bring back tight, predictable steering and secure wheel location with the Mevotech Supreme control arm CMS501037, a direct-fit replacement for the front left lower position on the 2004-2009 Cadillac XLR and 1997-2019 Chevrolet Corvette. It bundles the arm, its bushings, and an integrated ball joint into one Labor Saver™ unit to speed up the install. Engine specifics vary by application — see the Buyer's Guide tab to confirm your exact configuration.
This Mevotech Supreme suspension control arm uses cast aluminum construction to stay light and rigid to OE-level standards. If a worn control arm bushing or ball joint is behind clunking over bumps, loose or wandering steering, or uneven front tire wear, replacing this assembly addresses the failed component — diagnose the cause first, since these symptoms can have other sources.

What vehicles does the Mevotech Supreme lower control arm CMS501037 fit?
It's a direct-fit front left lower replacement for the 2004-2009 Cadillac XLR and 1997-2019 Chevrolet Corvette. Check the Buyer's Guide tab to confirm your exact engine and configuration.
Is this a complete control arm and ball joint assembly?
Yes — the arm, its bushings, and an integrated ball joint come as one unit, and a 90-degree SAE grease fitting plus a part-specific locking nut are included.
What are signs my Corvette control arm may need replacing?
Clunking over bumps, loose or wandering steering, and uneven front tire wear can point to a worn control arm bushing or ball joint. Diagnose the cause before replacing.
Does the ball joint come already installed?
Yes, the ball joint is integrated into the assembly and carries additional surface treatment that helps resist rust build-up for longer ball joint life.
Do I need to replace both sides?
This listing covers one front left lower arm. Suspension wear parts often wear together, so inspect the opposite side and replace both if worn for balanced handling.
