Delphi TC5999PX Suspension Control Arm and Ball Joint Assembly - Front Left Upper

Overview

Delphi Professional+ TC5999PX is a suspension control arm and ball joint assembly built for working vehicles that need stable alignment and consistent handling. It fits Chevrolet Colorado and GMC Canyon applications in the front left upper position, with fitment covering 2004-2012 model years.

Key Features

• Stamped steel control arm with a painted finish for durable service in harsh conditions.
• Pre-greased, greaseable design with a serviceable fitting for long-term maintenance.
• Includes the ball joint, bushings, dust boot, castle nut, cotter pin, and mounting hardware.
• Improved design grade with a bolt-in ball joint mounting type and threaded stud.
• Built with materials selected to reduce axial deflection under load and support alignment retention.

Detailed Description

The Delphi Professional+ line is aimed at fleet and work-truck use, where suspension parts see frequent load changes and rough road exposure. TC5999PX uses a stamped steel arm, rubber bushings, and a chloroprene rubber dust boot to support long service life, while the greaseable construction allows routine servicing. This part cross-references MOOG Chassis Products (e.g., RK620887) for the same application.

For Chevrolet Colorado and GMC Canyon owners, TC5999PX provides a direct replacement-style solution for the front left upper suspension position. The assembly is engineered to help maintain alignment, improve handling response, and reduce downtime associated with premature suspension wear.

What It Helps Address

• Loose or worn upper control arm joints.
• Alignment drift after suspension wear.
• Clunking or play from deteriorated bushings.
• Reduced steering stability under load.
• Premature wear from dry or unserviceable joints.

Installation Notes

Verify fitment by year, make, model, and front left upper position before installation. The bolt-in ball joint design and included mounting hardware support a straightforward replacement process, and the greaseable joint should be serviced according to the vehicle maintenance schedule after installation.

Quality Assurance

Delphi Professional+ chassis parts are built for demanding fleet and working-vehicle use, with serviceable components that can be regreased to extend part life and reduce downtime. Part number TC5999PX is engineered for durability and consistent suspension performance.
