Professional+ Front Lower Ball Joint

Delphi TC6122PX is a premium suspension ball joint for heavy-duty chassis service. It is built for front lower applications on Ram 2500 and Ram 3500 models, with greaseable service features and a press-in design for direct replacement work.

Key Features

  • Steel construction with a rubber dust boot for demanding road conditions.
  • Pre-greased and greaseable design for serviceable long-term operation.
  • Press-in mounting type with a threaded, tapered stud.
  • Castle nut, cotter pin, dust boot, and mounting hardware are listed in the product data.
  • Standard replacement suspension grade for chassis repair.

Detailed Description

The Delphi Professional+ line is built for fleet and working vehicles that see frequent load and road stress. This ball joint is engineered to minimize axial deflection under load, which helps maintain alignment and support more consistent handling. The serviceable design and premium materials are intended to extend part life and reduce downtime in demanding suspension applications. TC6122PX is a fitment-based replacement for Ram 2500 and Ram 3500 front lower suspension service, and the part number TC6122PX is also used in cross-reference listings such as MOOG K500351 for the same application.

What It Helps Fix

  • Excessive suspension play at the front lower joint.
  • Alignment drift caused by worn ball joint movement.
  • Clunking or looseness from a deteriorated chassis joint.
  • Grease loss or contamination at the joint area.
  • Premature wear in heavy-duty front suspension service.

Installation Notes and Tips

Fits 2014-2026 Ram 2500, front lower. Fits 2013-2026 Ram 3500, front lower. Verify press-in fitment, stud taper, and suspension configuration before installation. Use the included cotter pin and castle nut where specified by the application, and follow the vehicle service procedure for torque and alignment checks after replacement.

Quality Assurance

Delphi Professional+ chassis parts are developed for fleet and working-vehicle demands, with serviceable components that can be regreased to support longer service life. TC6122PX is built to help maintain alignment and reduce downtime in hard-use suspension applications.
