Professional+ Front Left Lower Control Arm

Delphi TC5574PX is a suspension control arm and ball joint assembly for heavy-duty service on compatible trucks and SUVs. It is built for the front left lower position and uses serviceable, greaseable components to support long-term suspension performance.

Steel control arm with casting/forged construction for strength under load
Pre-greased and greaseable design for easier maintenance
Press-in ball joint with threaded stud for secure assembly
Includes bushings, dust boot, castle nut, cotter pin, and mounting hardware
Painted finish with chloroprene rubber boot material for added protection

The Delphi Professional+ line is aimed at fleet and working vehicles that see frequent use and demanding road conditions. This assembly is engineered to minimize axial deflection under load, which helps maintain alignment and handling while reducing suspension wear. It is a direct-fit suspension control arm and ball joint assembly for Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500, and related applications, and the TC5574PX part number is commonly referenced in replacement searches for these vehicles.

Common Issues It Can Address

Excessive play in the lower control arm assembly
Alignment drift caused by suspension deflection
Clunking or looseness from worn ball joint components
Reduced handling stability under load
Premature wear from contaminated or dry suspension joints

Installation Notes and Tips

Verify fitment by year, make, model, and front left lower position before installation. Because this assembly uses a press-in ball joint and threaded stud, proper suspension service procedures and alignment checks are recommended after replacement. The TC5574PX should be matched to the vehicle application listed in the fitment data, including Chevrolet Suburban, Cadillac Escalade, and GMC Yukon variants where specified.
