Delphi TC4006 Suspension Control Arm and Ball Joint Assembly - Front Right Lower

OE-Style Front Right Lower Control Arm

Delphi TC4006 is a front right lower suspension control arm and ball joint assembly for select Ram 1500 models. It combines an aluminum control arm with a press-in ball joint, pre-greased components, and included bushings for a direct replacement on the front suspension.

• Part number: TC4006
• Aluminum control arm with casting/forged construction
• Ball joint included with press-in mounting and threaded stud
• Pre-greased, non-greaseable design
• Bushings, dust boot, mounting hardware, and locking nut included
• Black rubber bushings with chloroprene rubber dust boot material
• Uncoated finish with gray control arm color
• Clockwise (right) thread direction

Detailed Description

Delphi TC4006 is built for the front right lower position on 2019-2022 Ram 1500 trucks. It is a suspension control arm and ball joint assembly that includes the ball joint, bushings, dust boot, mounting hardware, and locking nut, helping streamline replacement of worn front suspension components. Delphi applies OE-focused dimensional and material analysis to support fitment consistency between original and aftermarket parts, and its steering and suspension components are tested across extreme temperature and salt-spray conditions.

This part cross-references Mevotech Supreme CMS251270 for the same application. Delphi TC4006 is a direct-fit option for Ram 1500 front suspension service when the original lower control arm shows wear, looseness, or noise.

What It Helps Address

• Front-end clunking or knocking from a worn lower control arm assembly
• Excessive play from a failing ball joint
• Uneven steering response caused by worn suspension pivot points
• Noise from deteriorated bushings in the front right lower suspension
• Restoring proper front suspension geometry on Ram 1500 models

Installation Notes and Tips

Verify the front right lower position before installation and compare the original part to TC4006 for mounting-hole layout, bushing dimensions, and ball joint orientation. Because this assembly uses a press-in ball joint and includes mounting hardware, replacement is typically performed as a complete unit rather than rebuilding individual wear items. A professional alignment is recommended after suspension work on a Ram 1500.

Quality Assurance

Delphi uses OE-based engineering, dimensional checks, and material analysis to support consistent aftermarket fitment. Its suspension and steering parts are subjected to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing.
