Prothane 1-1204-BL Rear Track Arm Bushing Kit Black Polyurethane

The Prothane 1-1204-BL is a rear track arm bushing kit designed to eliminate unwanted lateral sway and improve axle control on straight axle vehicles. Engineered from Prothane's proprietary polyurethane compound, these bushings deliver superior firmness and durability compared to factory rubber bushings, making them an ideal upgrade for demanding daily drivers, heavy-duty applications, and performance or race builds.

Track arm bushings (also known as track bar bushings or panhard bar bushings) are critical to keeping the rear axle centered under the vehicle. When OEM rubber bushings wear out, they allow excess side-to-side movement, resulting in a vague, wandering feel — especially noticeable on rough roads or during hard cornering. The Prothane 1-1204-BL restores precise axle location and steering response.

Key Features:

• Made from high-durometer black polyurethane for lasting performance
• Resists oils, solvents, and road chemicals that degrade OEM rubber
• Reduces axle side-to-side movement for improved handling and stability
• Suitable for heavy-duty and race applications
• Direct replacement for worn or deteriorated factory bushings
• Includes all necessary hardware for a complete installation

Prothane's polyurethane formulation maintains its shape and resilience far longer than OEM rubber, ensuring consistent suspension geometry and a more connected, confidence-inspiring driving feel over the life of the part.
