J.C. Whitney TD28900002 Front Track Bar OEM Replacement (Mopar 52121940AB)

The J.C. Whitney TD28900002 is a front suspension track bar designed as a direct OEM replacement, cross-referencing Mopar part number 52121940AB. This track bar is engineered to restore factory suspension geometry and steering precision to your Ram 2500 or Ram 3500 heavy-duty truck.

The track bar is a critical front suspension and steering component on straight-axle trucks. It laterally locates the front axle relative to the frame, and any wear or play in the bar or its bushings is immediately felt through excessive steering input, a wandering front end, or instability at highway speeds. Replacing a worn track bar with a quality OEM-spec unit restores proper axle alignment and confident steering feel.

Key Features:

• Direct OEM replacement — engineered to factory specifications
• Cross-references Mopar part number 52121940AB
• Restores factory front axle lateral positioning and steering geometry
• Front suspension placement — 4WD applications
• Designed for Ram 2500 and Ram 3500 trucks (excluding Power Wagon Off-Road Group)
• Approximately 41.5 inches in length

This track bar is a straightforward bolt-on replacement that brings your front suspension back to OEM specifications, eliminating the vague steering feel and instability associated with a worn factory unit. Compatible with non-Power Wagon Ram 2500 and Ram 3500 trucks.
