Restore tight, precise handling with the Mevotech TTX control arm, part number CTXMS501055 — a front left lower control arm and ball joint assembly engineered for high-usage commercial and passenger vans, SUVs, fleets and working trucks. It drops in as a direct-fit replacement for 2003-2025 Chevrolet Express 2500 and 3500, 2009-2025 Chevrolet Express 4500, 2003-2025 GMC Savana 2500 and 3500, and 2009-2024 GMC Savana 4500 (see the Buyer's Guide tab for engine-level details).
- Superior toughness: patented sintered bearings deliver longer-lasting performance.
- Built-in protection: a corrosion-sealing boot is integrated into the ball joint, and a 180-degree SAE grease fitting is included for simple servicing.
- Secure fit: added knurling locks the control arm bushing to the sub-frame, while an application-specific ball stud system with a larger sphere optimizes performance.
- Easy installation: includes a part-specific slotted castle nut and snap cotter pin, and a thicker, stronger flange helps prevent deformation during install.
Cast steel construction is engineered to meet or exceed OE specifications. If a worn control arm bushing or ball joint is the cause of clunking over bumps, wandering steering, or uneven front tire wear, this assembly replaces both in a single unit.
