Prothane 6-309 Rear Trailing Arm Bushing Kit for 1979-2003 Ford Mustang

Upgrade the rear suspension of your 1979-2003 Ford Mustang with the Prothane 6-309 Trailing Arm Bushing Kit. Designed for the rear axle housing, this kit replaces worn or deteriorated factory bushings with durable polyurethane components that help improve suspension control, handling response, and overall driving stability. The hard red polyurethane construction is engineered to resist common causes of bushing failure, including compression, deformation, and exposure to automotive fluids.
The Prothane 6-309 kit combines polyurethane bushings with steel components finished in zinc oxide for added durability and corrosion resistance. Its application-specific design supports consistent suspension movement while helping reduce unwanted flex in the trailing arm connection. This makes it a practical choice for street performance builds, restoration projects, and drivers seeking more responsive rear suspension behavior without replacing the complete trailing arm assembly.
Designed for compatible 1979-2003 Ford Mustang applications, the Prothane 6-309 rear trailing arm bushing kit provides a dependable solution for refreshing the axle housing mounting points. The distinctive hard red finish offers easy visual identification, while the robust materials are suited to demanding everyday and performance-oriented use. Confirm vehicle compatibility and installation requirements before ordering to ensure proper fitment.
